Finding the average of the four numbers is an example of__processing___.
Telling the user the average is an example of__output___.
Explanation:
Following are the discussion to the given question:
Input is displayed by asking users for four digits. Any data or information that's also supplied to a system for analysis is referred to as input. Its statement, 'input' tells the system that it uses must enter some data before the software can proceed.The instance of processing is computing the mean of four numbers. In the CPU, computing is the conversion of input information to a more meaningful form of information.An instance of output is giving the user the average. It refers to information produced by and sent through a computer or another electronic device. The act of generating it, the amount generated, or the procedure through which something is given are all instances of output.Therefore, the answer is "input, processing, and output".

Write a program with three functions: upper , lower , and reverse . The upper function should accept a pointer to a C-string as it's only argument. It should step through each character in the string, converting it to uppercase. The lower function, too, should accept a pointer to a C-string as it's only argument. It should step through each character in the string, converting it to lowercase. Like upper and lower , reverse should also accept a pointer to a string as it's only argument. As it steps through the string, it should test each character to determine whether it is upper- or lowercase. If a character is uppercase, it should be converted to lowercase. Likewise, if a character is lowercase, it should be converted to uppercase. Test the functions by asking for a string in function main , then passing it to them in the following order: reverse, lower , and upper. Main will then print out the strings to demonstrate the functions worked. Each function accepts exactly one argument. None of the functions return anything. None of the functions (other than main) interacts with the user in anyway. Variables of type string are not allowed.
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
#include <cstring> //to manipulate C-strings
#include <string> //to manipulate strings
using namespace std; //to access objects cin cout
//function prototypes
void upper(char *); to convert to upper case
void lower(char *); //to convert to lower case
void reverse(char *); //to convert to reverse case
int main() { //start of main method
char input[101]; //creates a char type array to hold input string
cout << "Enter a string: "; //prompts user to enter a string
cin.getline(input, 101); //reads input string from user
upper(input); //calls upper() method to convert the string to upper case
lower(input); //calls lower() method to convert the string to lower case
reverse(input); } //calls reverse() method to convert the string to reverse case
void upper(char *cString){ //method that takes a pointer to a C-string as it's only argument and converts that string to upper case
cout << "String in upper case: "; //displays string in upper case
for(int i = 0; i < strlen(cString); i++){ //iterates through the input string cString until the length of the cString is reached
if(islower(cString[i])) //checks if the character at i-th index of cString is in lower case
cout << (char) toupper(cString[i]); //converts each i-th character of cString to upper case at each iteration
else //if no character of cString is in lower case
cout << cString[i]; } //displays the cString as it is
cout << endl;} //prints a new line
void lower(char *cString){ //method that takes a pointer to a C-string as it's only argument and converts that string to lower case
cout << "String in lower case: "; //displays string in lower case
for(int i = 0; i < strlen(cString); i++){ //iterates through each character using for loop first character to last
if(isupper(cString[i])) //checks if the character at i-th index of cString is in upper case
cout << (char) tolower(cString[i]); //converts each i-th character of cString to lower case at each iteration
else //if no character of cString is in upper case
cout << cString[i]; } //displays the cString as it is
cout << endl; } //prints a new line
void reverse(char *cString){ //method that takes a pointer to a C-string as it's only argument and converts that string to reverse case (upper to lower and vice versa)
cout << "String in reverse case: "; //displays string in reverse case
for(int i = 0; i < strlen(cString); i++){ //iterates through each character using for loop first character to last
if(isupper(cString[i])) //checks if the character at i-th index of cString is in upper case
cout << (char) tolower(cString[i]); //converts character at i-th position of cString to lower
else //if the character is in lower case
cout << (char) toupper(cString[i]); } //converts character at i-th position of cString to upper
cout << endl;} //prints a new line
Explanation:
I will explain the program with an example.
Lets suppose user enters "hi" as input. So
Now first upper() method is called by passing this C-string to it.
It has a for loop that checks at each iteration, if a character of C-string is in lower using islower method which returns true if the character is in lower case. Since both the characters 'h' and 'i' are in lower in case so they are converted to upper case at each iteration using toupper() method. So the output of this part is:
String in upper case: HI
Now next lower() method is called by passing this C-string to it.
It has a for loop that checks at each iteration, if a character of C-string is in upper using isupper method which returns true if the character is in upper case. Since both the characters 'h' and 'i' are in lower in case so the string remains as it is. So the output of this part is:
String in lower case: hi
Now next reverse() method is called by passing this C-string to it.
It has a for loop that checks at each iteration, if a character of C-string is in upper using isupper method which returns true if the character is in upper case. Since both the characters 'h' and 'i' are in lower so else part: cout << (char) toupper(cString[i]); executes which converts these characters to upper case (reverse case). So the output of this part is:
String in reverse case: HI

Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from the keyboard.Tell the user how much change is owed and number of quarters, dimes, nickels, and pennies in change a customer would receive.Pay special attention to roundoff error. Your program should use division and modular division. No if’s or loops may be used. You may assume all change will be a positive number with no more than two decimal places. If more than $1.00 is owed, the full value should be included in the number of quarters returned. For example, $2.50 should be returned as 10 quarters.Hint: Modular division is a great way to find the remainder of a division. Think about how you can use this to calculate the change that is left over after some coins are given.Sample Run:Please Enter the Cost of the Item:4.57Please Enter the Amount Paid:5.00Change Owed: 0.43Quarters: 1Dimes: 1Nickels: 1Pennies: 3
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { // class name
public static void main(String [] args) { // start of main method
Scanner input = new Scanner(System.in); // creates Scanner class object to take input from user
System.out.println("Please Enter the Cost of the Item: "); // prompts user to enter the cost of item
double itemCost = input.nextDouble(); //scans and reads the input value of item cost
System.out.println("Please Enter the Amount Paid: "); // prompts user to enter the amount paid
double amount = input.nextDouble(); //scans and reads the value of amount from user
int change = (int)(amount * 100 - itemCost * 100); //compute the remaining amount i.e. change
System.out.println("Change Owed: " + change / 100.0); // displays the owed change
int quarters = change / 25; // computes the value for quarters
change = change % 25; // compute the quarters remaining
int dimes = change / 10; // computes dimes
change = change % 10; // computes dimes remaining
int nickels = change / 5; // computes nickels
change = change % 5; // compute nickels remaining
int pennies = change; // computes pennies
System.out.println("Quarters: " + quarters); // displays computed value of quarters
System.out.println("Dimes: " + dimes); // displays value of dimes
System.out.println("Nickels: " + nickels); // displays value of nickels
System.out.println("Pennies: " + pennies); }} //displays value of pennies
Explanation:
I will explain the program with an examples.
Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:
Change is computed as
change = (int)(amount * 100 - itemCost * 100);
This becomes;
change = (int)(5.00 * 100 - 4.57 * 100)
= 500 - 457
change = 43
Now the change owed is computed as:
change / 100.0 = 43/100.0 = 0.43
Hence change owed = 0.43
Next quarters are computed as:
quarters = change / 25;
This becomes:
quarters = 43/25
quarters = 1
Now the remaining is computed as:
change = change % 25;
This becomes:
change = 43 % 25;
change = 18
Next the dimes are computed from remaining value of change as:
dimes = change / 10;
dimes = 18 / 10
dimes = 1
Now the remaining is computed as:
change = change % 10;
This becomes:
change = 18 % 10
change = 8
Next the nickels are computed from remaining value of change as:
nickels = change / 5;
nickels = 8 / 5
nickels = 1
Now the remaining is computed as:
change = change % 5;
This becomes:
change = 8 % 5
change = 3
At last the pennies are computed as:
pennies = change;
pennies = 3
So the output of the entire program is:
Change Owed: 0.43 Quarters: 1 Dimes: 1 Nickels: 1 Pennies: 3
The screenshot of the output is attached.
Which function will add a name to a list of baseball players in Python?
append()
main()
print()
sort()
Answer: B I took the test
Explanation:
The function that will add a name to a list of baseball players in Python is main(). The correct option is b.
What is python?Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Python is a general-purpose language, which means it may be used to make many various types of applications and isn't tailored for any particular issues.
A function is a section of code that only executes when called. You can supply parameters—data—to a function. The main() function in Python serves as the point at which any software application is executed.
Since the program only runs when it is executed directly, and not if it is imported as a module, the execution of the program can only begin when the main() function is declared in Python.
Therefore, the correct option is b, main().

Write a program that utilizes the concept of conditional execution, takes a string as input, and: prints the sentence "Yes - Spathiphyllum is the best plant ever!" to the screen if the inputted string is "Spathiphyllum" (upper-case) prints "No, I want a big Spathiphyllum!" if the inputted string is "spathiphyllum" (lower-case) prints "Spathiphyllum! Not [input]!" otherwise. Note: [input] is the string taken as input.
Answer:
Written in Python
inputt = input()
if inputt == "SPATHIPHYLLUM":
print("Yes - Spathiphyllum is the best plant ever!")
elif inputt == "spathiphyllum":
print("No, I want a big Spathiphyllum!")
else:
print("Spathiphyllum! Not"+ inputt+"!")
Explanation:
This line gets user input
inputt = input()
This line checks if input is uppercase SPATHIPHYLLUM and executes the corresponding print statement, if true
if inputt == "SPATHIPHYLLUM":
print("Yes - Spathiphyllum is the best plant ever!")
This line checks if input is uppercase spathiphyllum and executes the corresponding print statement, if true
elif inputt == "spathiphyllum":
print("No, I want a big Spathiphyllum!")
If user input is not upper or lower case of Spathiphyllum, the following if condition is considered
else:
print("Spathiphyllum! Not"+ inputt+"!")

Explanation:
You need to control the number of people who can be in an oyster bar at the same time. Groups of people can always leave the bar, but a group cannot enter the bar if they would make the number of people in the bar exceed the maximum of 100 occupants. Write a program that reads the sizes of the groups that arrive or depart. Use negative numbers for departures. After each input, display the current number of occupants. As soon as the bar holds the maximum number of people, report that the bar is full and exit the program.
Answer:
count = 0
while True:
people = int(input("Enter the number of people arrived/departed: "))
count += people
if count == 100:
print("The bar is full")
break
elif count < 100:
print("There are " + str(count) + " in the bar currently")
else:
print(str(people) + " people cannot enter right now")
print("The maximum capacity is 100!")
count -= people
print("There are " + str(count) + " in the bar currently")
Explanation:
*The code is in Python.
Set the count as 0
Create an indefinite while loop.
Inside the loop:
Ask the user to enter the number of people arrived/departed
Add the people to the count (cumulative sum)
Check the count. If the count is 100, stop the loop. If the count is smaller than 100, print the current number of people. Otherwise, state that they cannot enter right now. The capacity is 100 at most. Subtract the people from the count and print the current number of people.
