why printf works on non-terminated string

Question

I am wondering how does printf() figure out when to stop printing a string, even I haven\'t put a termination character at the end of the string? I did an experiment by mall

Answer 1

The random garbage that is after the last byte in the string was null. It was luck. It could fail the next time you run the program or work 100 times in a row. Welcome to pointer errors (and they can be difficult to debug too).
