Thread: about fuction!

in the main i there is a part that will go to checking()
i want after that will go back again to main

Code:

checking(){
for(i = 0;i < 26; i++){
		if (o_brief[n] == (i+1))
		{
			gotoxy(x[i], y[i]);
			printf("  ");
		}
	}

	for(i = 0;i < 26; i++){
		if(c_brief[o_brief[n]-1]==z[i])
		{
			gotoxy(65,23);
			printf("%8ld",z[i]);
			sleep(2);
			gotoxy(65,23);
			printf("          ");
			gotoxy(d[i], e[i]);
			printf("*");
		}
	}
}

main(){
	gotoxy(30,20);
	printf("Choose your briefcase!");
	gotoxy(10,23);
	scanf("%d",&y_brief);

	for(i = 0;i < 26; i++){
		if(y_brief==1+i)
		{
			gotoxy(x[i], y[i]);
			printf("  ");
		}
	}

	gotoxy(29,20);
	printf("      Round 1        ÚÄÄ¿    ");
	gotoxy(29,21);
	printf("                     ³  ³    ");
	gotoxy(29,22);
	printf("Open 6 briefcases!   ÀÄÄÙ    ");

	do{
	gotoxy(51,21);
	scanf("%d",&o_brief[n]);
	gotoxy(51,21);
	printf("  ");

        checking();

	resume here

	sum[0]=sum[0]+c_brief[o_brief[n]-1];
	n++;
	}while(n<6);
	r[0]=rand() % ((15 - 5) + 1) + 5;
	offer[0]=((7020566 - sum[0]) / 20) * (r[0] / 100);

	gotoxy(29,19);
	printf("    banker offers you         ");
	gotoxy(29,20);
	printf("     ÚÄÄÄÄÄÄÄÄÄÄÄÄÄ¿          ");
        gotoxy(29,21);
	printf("     ³             ³          ");
	gotoxy(29,22);
	printf("     ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÙ          ");
	gotoxy(37,21);
	printf("%7.0lf",offer[0]);
	gotoxy(29,23);
	printf("   [D]eal or [N]o Deal        ");

	Resp=getch();
	if(Resp==100){
	closed(g=0);
	}
	else
	briefcases2();
}

Functions always return to where they were called from.

Just call main(). But even at that, I would not highly recommend a recursive main() function. Why not have main() call your game function. And have your game function be a callback type of function that has information given to it through main.

Example:

Code:

struct game_variables
{
  ... // I will leave this up to you
}

int in_game(struct game_variables *pvars)
{
  ... // have it return zero to stop execution of the game or non-zero for other scenarios.
}

int main(void)
{
  struct game_variables vars;

  ... // initialize and do whatever

  while(in_game(&vars))
  {
     // you could also store the return of in_game and process the return value if the returns
     // are designed to have any specific significance.
  }

  return 0;
}

The two ways I do this is:

1) Make a do while loop in main() that is large enough to put all your other function calls, inside it.

something like this:

Code:

gameon = 1;
do   {
//other game function calls in here

   if(briefcases_left < 1 || deal == 1)
      gameon = 0;

}while(gameon == 1);

Or

2) have main() call a driver or menu function, and put the same type of large game loop,
into that function, like the above code fragment.

Either way, you avoid recursively calling main() - which may be allowed, but is certainly a bad programming practice.
