why while(10) excuate body infinity times ???

[waqas qayum]

what does 10 means in while(10) and why it excuate infinity times like while (1) iz 10 also means true same like 1 ?????

while(10) is the same as while(1) or any other symbolic constant.

It means that the loop runs forever.

You usually see this in a menu driver:

int choice;
while(1)
{
 
  choice = getChoice();
  switch (choice)
  {
     case 1:
       ..this is menu choice 1...
       break;
     case 2: 
       .. this is menu choice 2..
       break;
     default:
        ...this is a bad choice..
     }
}
  }

The program will stay in this loop for all choices. Hopefully, of choice is to exit the program or you are going to be here a looonnnggg time.

yes in C programming loop has two possibilities
1)true -i.e. any non-zero values are considered as true
2)false -i.e. only value zero is used to end the loop
Note:Its nice practice to use while(10)
but you must take care that you explicitly mention a break statement to avoid infinte loops

The break statement I used was for the switch inside the loop. The loop is intended to be infinite so process always returns back to the menu.

There is nothing wrong in using infinite loops.

could you please elaborate why it is not wrong?

[yannifan01]

It is not wrong if you want to program to run always.

[techboy]

how is it sounds run always.No one wants the program to be forever it always has to some day terminate to give some results!

Did you ever notice that Windows always runs?

[techboy]

No it would be honour if you can explain me ?
