How to copy a string into a char array in C++ without going over the buffer

Question

I want to copy a string into a char array, and not overrun the buffer.

So if I have a char array of size 5, then I want to copy a maximum of 5 bytes from a string in

Answer 1

i think snprintf() is much safe and simlest

snprintf ( buffer, 100, "The half of %d is %d", 60, 60/2 );

null character is append it end automatically :)
