I'm sorry if this question has been asked before, but I'm struggling with figuring out how to google it right. I don't know how to pose the question without an example.
Say I have this code:
int main(){
int * ptr = NULL;
int input = 0;
cin >> input;
if(input > 5)
ptr = new int;
/*Apparently this doesn't work..*/
if(ptr)
delete ptr;
return 0;
}
That's basically the way I've been checking if a pointer has been allocated dynamic memory or not, but I've just learned that my solution is wrong. So what might be one smart way to go about it? I just made the above code off the top of my head, so please don't criticize it for stuff that's off-topic from the question. Thanks a lot.
