Question

Write a C++ program that determines if an integer is a multiple of 7. The program should prompt the user to enter and integer, determine if it is a multiple of 7 by using a given formula and output the result. This is not meant to be a menu driven program so one run of the program will only offer one input and one output.

Answer 1

Answer:

#include <iostream>  // Needed for input/output operation

int main()  // define the main program

{

   int userNumber = 0; // number storage for user input

   std::cout << "Please enter an integer: ";  // Ask user for number

   std::cin >> userNumber;  // Assumes user input is an integer

   if (userNumber % 7 != 0)  // Check to see if 7 divides user input

       std::cout << "\nYour number is not a multiple of 7.\n";

   else

       std::cout << "\nYour number is a multiple of 7.\n";

   return 0;  // End program

}
