Thread: a question on 'printf'

Hi, everyone!

I've a simple question on 'printf' function. See the code below:

Code:

#include <stdio.h>
int main (void) {
  printf("this \n");
  printf("confused me\n"); // a breakpoint is set here.
  return 0;
}

After compiling the code, I set a breakpoint (see above) in GDB.

As expected, "this \n" is printed if the execution reaches the breakpoint.

If I remove '\n' in "this \n" and run the code as above. "this " will NOT be printed if the execution reaches the breakpoint.

So, this confused me a lot! Any help are highly appreciated! Thank you!

Thank you!
