Question

Write a program that takes a single integer input from the user and stores it in a variable. Your program should increase the value of this variable by one three times, printing "number is now " followed by its value each time, then decrease it by one three times, again printing "number is now " and the value each time

Answer 1

Answer:

Question is answered using python:

num = int(input("User Input: "))

for i in range(3):

    num = num+1

    print("Number is now "+str(num))

for i in range(3):

    num = num-1

    print("Number is now "+str(num))

Explanation:

This line prompts user for input

num = int(input("User Input: "))

The following iterates from 1 to 3

for i in range(3):

This increments user input each time

    num = num+1

This prints the value of num after increment

    print("Number is now "+str(num))

The following iterates from 1 to 3

for i in range(3):

This decrements the value of num

    num = num-1

This prints the value of num after decrement

    print("Number is now "+str(num))
