Help me connect my functions

[tripline]

How does the compiler choose which function to run first?
If I choose not to Play, I want my main() to run.

#include <iostream>
#include <ctime>
using namespace std;

int playGame()
{
int count =0; int random = (rand()%10)+1; int choice;

for(int i=0;i<3;i++)
{
cout << "Guess the number 1-10: ";
cin >> choice;
	if (random==choice)
	{
	cout << "you guessed it right!" <<endl;
	count=i+1; break;
	}
	else if (i==2)
	{
	cout << "you lose!" <<endl;
	count--; break;
	}
	else  
	{
	cout << "Guess again!"<<endl;
	}
}
return count;
}

int wantToPlay(int*win, int*loss)
{
bool perfPlay = true; char option;

while (perfPlay)
	{
		cout << "Would you play to (P)lay or (Q)uit?";
		cin >> option;	
		if (option == 'p' || option == 'P')
		{
		int count=playGame();
			if(count > 0)
			win++;
			else
			loss++;
		}
		else
		{perfPlay =false;}
	}    
return 0;
}

int main()
{ 
	int a; 
	int b;
	wantToPlay(&a,&b);
	cout << "You have won " <<a << " games and lost " <<b <<" games"<<endl;
return 0;
system("pause");
}

That's what your code does though.

If I choose Q to quit, the game exits.
cout << "You have won " <<a << " games and lost " <<b <<" games"<<endl;
does not occur

It does, but the program exits immediately after, the dialog may close before you can read it (depending how you are running the program). Also, you need to initialize 'a' and 'b' to 0 in main. Also, you should rename them something meaningful (wins, losses perhaps).

You tell it the order! It calls functions in the order you called them! No picking and choosing!

[tripline]

What makes the program choose to do wantToPlay() before doing main()? Because main called wantToPlay?

[tripline]

I added system("pause"); but the cmd prompt still exits. Also, in Visual Studio, to keep the cmd line running, is it

Project > Properties > Config Properties > Linker > System > Subsystem > Console?

main is always executed, it is the entry-point of ALL C++ programs.

tripline, the 2 solutions I use are to either
1) run the program with ctrl+f5 instead of f5
2) end the program with something like "cin >> randomVariable;"

You could also add something like "Sleep(5000)" (Windows.h) if you wanted.
