Write code that prompts the user to enter a positive nonzero number and validates the input.
Write a code snippet that prompts the user for an integer named number and prints out “Good Number” if the input meets any one the following conditions, and prints out “Bad Number” if it does not :
number equals 5
number equals 7
number is between 10 and 20 (non-inclusive)
number is greater than 30.
-Prompts the user to enter an integer x. Assume without error checking the user enters a positive integer.
-The program then will print all the odd integers between 1 and x that are a multiple of 3.
Sample:
Enter an integer x: 15
3 is a multiple of 3
9 is a multiple of 3
15 is a multiple of 3
