How to return 2 variables ?

[newdomingo]

Hi,

my question is how to return 2 variables, one integer and one double, from a function ?

(pseudocode) i have a function :

int fun(){
 int x;
 double y; 

 //computations
 //...

 return x, y; 
}

Any help please ?

Thanks !

Something like this?

struct COMBO
{
     int x;
     double y;
};

And make the return type for the function the type for your object.

yes, right probably another solution could be to make one of those variables global.

pair<int, double> fun(){
 int x;
 double y; 

 //computations
 //...

 return make_pair(x, y); 
}

@Cubbi

how to call the function fun() from main() ?

i mean for example when we have:

int fun(){
 int x; 

 //computations
 //...

 return x; 
}

int main(void){
  int y;
  y = fun(); // here i call function fun() 
  return 0;
}

when we have

pair<int, double> fun(){
 int x;
 double y; 

 //computations
 //...

 return make_pair(x, y); 
}

how to call this function from main() ?

In this case,

  int y;
  y = fun().first;

could also be

int x;
double y;
pair<int, double> p = fun();
x = p.first;
y = p.second;

or

int x;
double y;
tie(x, y) = fun();
