Re: [Dev-C++] RE: Printing

[Per W. <pw...@ia...>]

The compiler always zero-terminate strings if you just give it a chance.

char mystr[] = "foobar";

will store six characters and a termination. It's whey you try

char mystr[6] = "foobar";

that you might get into problems, since the array doesn't allocate space
for a termination. A lot of compilers will complain.
