For example
I have char str[1024];
And I will do memset(str,0,1024); later
Is this okay,?
OR
i need to do this:
char* str = new char[1024];
thanks.

As @HostileFork already pointed out, you probably want
std::stringhere. If whatever you’re doing isn’t particularly string-like, then you may wantstd::vector<char> str(1024);instead.Either way, you it’s quite certain you don’t want
new char[1024](a leftover from an early era of C++ that probably wouldn’t be in the language at all if other facilities were present) and probably don’t wantchar str[1024];either, though there’s at least some possibility that this one isn’t an egregious mistake.
