how to return values i c++ code example

Example 1: function return with int c++

#include <iostream>
 
int getValueFromUser()
{
 	std::cout << "Enter an integer: ";
	int input{};
	std::cin >> input;  
 
	return input;
}
 
int main()
{
    int x{ getValueFromUser() }; // first call to getValueFromUser
    int y{ getValueFromUser() }; // second call to getValueFromUser
 
    std::cout << x << " + " << y << " = " << x + y << '\n';
 
    return 0;
}

Example 2: return function in cpp

// Single return at end often improves readability.
int max(int a, int b) {
    int maxval;
    if (a > b) {
        maxval = a;
    } else {
        maxval = b;
    }
    return maxval;
}//end max
