Answers for "c++ return value from function"

return use in c++

Terminates the execution of a function and returns control to the calling function (or to the operating system if you transfer control from the main function). Execution resumes in the calling function at the point immediately following the call

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;
}
