null terminating a string

Question

gcc 4.4.4 c89

What is the standard way to null terminate a string? When I use the NULL I get a warning message.

*dest++ = 0; 
*dest++ =

'\0' is the way to go. It's a character, which is what's wanted in a string and has the null value.

When we say null terminated string in C/C++, it really means 'zero terminated string'. The NULL macro isn't intended for use in terminating strings.
