Thread: Nulling an array

But I like that struct initializing method instead of calling in a function, how do I use that for modifying just one specificied member? Tried nulling the remaining members but some are arrays with pointers and it gives all sorts of errors

And that's presumably the size of the array?

You can't do that. Initialization like was suggested early on in this thread is ONLY possible when you declare the variable itself.

If, inside the code, you need to fill the array with a value (such as zero), then memset is the option.

Ah memset, that seemed to work, thanks !

Boom! Buffer overflow!
You are using the index operator to access the 51th element there. And ONLY that element to boot, nothing else.
Be careful with those arrays! Buffer overruns are very bad.
All arrays goes from 0 to size - 1.

Yea well in my program I didn't have it as 50, I had it at 1000, I was just using random numbers, lol.

OK, so you avoided a buffer overrun. That's good
But using random numbers everywhere doesn't make much sense, does it?

I just gave it 1000 because I knew there was no way 1000 elements would be used
