quick C question
« on: 1 July 2003, 14:00 »
I'm having a problem with this:

Code: [Select]

It gives the output:

Code: [Select]

I think there is a problem with my while statement. I did it with for just fine, I'm just thinking I can do it with while too.

I probably look stupid, but I'm trying to brush up on some C skills.

Actually, I find ET to be extremely easy even without beer and pizza... however, I need vast amounts of drugs at 2 am in the morning

The commas are the problem: these should be semi's.

That's correct for the for() function. I figured it all out, I was using while() way wrong. Now to figure out how to take some chars out of a string and use them.

char *buf1="abcdefg";
how do we make buf2="cdef"?

strncpy(buf2, buf1 + 2, 4);
