exiting a while loop with a negative integer

I want to exit a while() when the user enters a negative number of any size. What kind of condition would I need at the start of the loop to get the loop to exit w

Answer 1

Do not define your variable as unsigned variable. As suggested in other answers use if statement and break with if statement.

example:

int main(void)
{
 int i;
 while(1){
 /*here write an statement to get and store value in i*/ 
  if(i<0)
  {
    break;
  }
 /*other statements*/
  return(0);
  }
 }
