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

#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 << "\\Your number is not a multiple of 7.\\";

else

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

return 0; // End program

}
