Previous and next
Write a program that reads an integer number and prints its previous and next numbers. See the examples below for the exact format your answers should take. There shouldn't be a space before the period.
Remember that you can convert the numbers to strings using the function str.
Input Correct answer
179 The next number for the number 179 is 180.
The previous number for the number 179 is 178.
0 The next number for the number 0 is 1.
The previous number for the number 0 is -1.
100 The next number for the number 100 is 101.
The previous number for the number 100 is 99.
Assuming that the code is in python, this would be your answer:
The code is simple. You just have to take a variable and return the number 1 above it and the number 1 below it. The final code would look like this:
num = int(input()) print('The next number for the number ' + str(num) + ' is ' + str(num + 1) + '.') print('The previous number for the number ' + str(num) + ' is ' + str(num - 1) + '.')
