Question get exit status from a C-program in Bash

In Bash I can get the exit status from commands, functions and scripts (with $?). But for some reasons I can't get the exit status from my own C-programs (I get always the same status, even if I exit with another value). Do I need to compile my C-programs with certain options? What am I doing wrong? Or what can I do?

Have you just tried compiling a simple program? i.e. does this work:

C Code
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
printf("Hello, world!\n");

  if( !strcmp( argv[1], "Success" ) )
     return 0;
     return 1;
Bash Script
./testc Success
echo "Return status was: " $?

./testc fail
echo "Return status was: " $?
My output was
Hello, world!
Return status was:  0
Hello, world!
Return status was:  1
