This is just a code for one question of a game I'm creating, its family feud. Now at the end, I get the sum of scores of 1 team, but I want the sum of scores of both teams to appear separately. how do I do that?
and i want them to appear seperately so that i could get sum from all questions and then compare the scores.

Answer 1

You can use std::pair as return.
std::pair <std::string,double> a (var1,var2);
return a;

Answer 2

You can only return a single object from a function. It is not possible to return multiple objects. However, an object can have sub-objects and you can return an object whose sub-objects are the two separate results that you desire.
What you can do is define a custom type, that consists of multiple values. In C++ and in object oriented programming in general, such structure is called a class. An example class:
struct results {
int team1, team2;
};
You can define a function that returns an instance of results which contains the two values that you need.

Answer 3

Something you can also do is use "out variables", basically passing variables by reference to functions as arguments:
void Round3(int& team1Score, int& team2Score)
{
// Do your score calculations
team1Score = /*However you would normally calculate the score for team1*/
team2Score = /*However you would normally calculate the score for team2*/
}
It can then be used like this:
int main()
{
int score1;
int score2;
Round(score1, score2);
// score1 and score2 are now filled with the values calculated in Round3()
return 0;
}
