Thread: getchar() help

In the following code snippet

Code:

while(1)
    {
        char c;
        printf("enter y/n");
        c=getchar();
        if(c=='y')
            continue;
        else
            break;
    }

the getchar() doesn't work in the second iteration.Why is that?

Okay..is there any way to override that and keep the loop running until a char input 'n' is entered?

Well the problem is the solution in this case. Read all of the input. One getchar will read the interesting character, and another call will read the \n, which you are free to ignore.

Hmm I may be wrong, but aren't continue and break statements "forbidden" in if-else statements ?

No, the code makes sense.

Code:

while forever:
  if c is y:
    continue the loop
  else:
    break it
end while
