control statements in c Infinite looping controls

Why you are using infinite loop in while and do while inside 1 only? and why can't I put any value?

Infinite loops are common in menu based applications where you want to return to the menu until the exit choice is selected.

I have the entire program inside an infinite loop:

int main()
{
     while (1)
     {
       Program();
     }
{

If Program() returns, it is just restarted.

I think your question is why do people use "while(1)" instead of "why(42)"?
The convention is to use "1" even though any nonzero constant would do the same thing.
