OK, so on my program, whenever I enter in incorrect selection (when I am actually running it), it goes back to the main loop and continually loops! what's wrong with it? here's the code:

#include <iostream>
#include <windows.h>
using namespace std;
void setcolor(unsigned short color) //The function that you'll use to
{ //set the colour
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);
}
int main()
{
system ("title Calculator");
loop:
system ("cls");
setcolor (10);
cout << "Menu\n\n";
setcolor (7);
cout << "1) Subtraction\n2) Multiplication\n3) Addition";
cout << "\n4) Division...\n";
int menu;
cout << "\n\nYour selection: ";
cin >> menu;
if ( menu == 1) { // If "menu" equals 1...
setcolor (12); //Set the color to red
long int subnum1;
cout << "\nYour first number to subtract? ";

cout << "[Press any key to continue]";
system ("pause >nul");
goto loop;}
if ( menu == 2) {
setcolor (3);

cout << "\nYour first number to multiply? ";

return 0;
}
}
