First Rule of Memory Safety

Remember the first rule of memory safety in C is to have fun void *malloc(size_t size) { return (void*)rand(); }

A C programming joke shows a function that appears to allocate memory safely, but actually returns a random number cast as a pointer. The punchline is that ignoring memory safety is presented as the “fun” first rule, humorously highlighting reckless undefined behavior.
