Return Multiple Values C++

Question

Is there a way to return multiple values from a function? In a program I'm working on, I wish to return 4 different int variables to the main function, from a separate function, all stats needed to continue through the program. I've found no way to really do this. Any help would be greatly appreciated, thanks.

Answer 1

One solution could be to return a vector from your function :

std::vector<int> myFunction()
{
   std::vector<int> myVector;
   ...
   return myVector;
}

Another solution would be to add out parameters :

int myFunction(int *p_returnValue1, int *p_returnValue2, int *p_returnValue3)
{
   *p_var1 = ...;
   *p_var2 = ...;
   *p_var3 = ...;
   return ...;
}

In the second example, you'll want to declare the four variables that will contain the four results of your code.

int value1, value2, value3, value4;

After that, you call your function, passing the address of each of your variables as parameters.

value4 = myFunction(&value1, &value2, &value3);

EDIT : This question has been asked before, flagging this as duplicate. Returning multiple values from a C++ function

EDIT #2 : I see multiple answers suggesting a struct, but I don't see why "declaring a struct for a single function" is relevant when their are obviously other patterns like out parameters that are meant for problems like this.
