Q1

Split the following program into two files (main.cpp, and input.cpp). main.cpp should have the main function, and input.cpp should have the getInteger function.

#include <iostream>

int getInteger()
{
	std::cout << "Enter an integer: ";
	int x{};
	std::cin >> x;
	return x;
}

int main()
{
	int x{ getInteger() };
	int y{ getInteger() };

	std::cout << x << " + " << y << " is " << x + y << '\n';
	return 0;
}

Solution#

main.cpp

#include <iostream>

int getInteger();

int main()
{
    int x { getInteger() };
    int y { getInteger() };

    std::cout << x << " + " << y << " is " << x + y << '\n';

    return 0;
}

input.cpp

#include <iostream>

int getInteger()
{
    std::cout << "Enter an integer: ";

    int x {};
    std::cin >> x;

    return x;
}
