The break and the endless cycle

We saw recently the for loop , and found that its structure was as follows:

for (start, end; increase)

What happens if we no beginning or end? Then we get an infinite loop, like this:

for (;;)

And how do you stop? For a break, like this:

for (;;)
{
break;
}

And this for me to use? For the idea is to repeat the instructions until the user wants to, ie:

 # Include <stdio.h>
 # Include <conio.h>
 int main ()
 {
   char end = 0;
   for (;;)
   {
     gotoxy (5, 5); printf ("I want to quit? (y / n):") scanf ("% c", & end);
     if (end == 'y')
       break;
     ClrScr ();
   }
 } 

I do not think I had mentioned that if within an if condition is only one instruction is not necessary to put keys, and also applies to the cycles.

If the user does not enter a 'y', the program never stops. Then we will see that the properties of aninfinite loop is very similar to the while loop to be discussed later.
