Question

Very simple example – hoping for a simple solution:

char x[7];
if(fgets(x,5,stdin))
    printf("y");
else
    printf("n");

I can’t seem to get it to print “n” when I input more than the byte limit – is there any simple way I could enforce it or catch when it’s surpassed?

As a side question, what example inputs would actually cause an “n” in the above snippet? I’m not really seeing the point right now..

Cheers,

fgets returns NULL only if it failed to read anything, which usually means end of file.

Since fgets reads a line, or as many characters of that line that fit in the buffer, you need to check if your variable x contains a newline character.
