Re: Feedback on C code?
So, I've been learning all about how pointers are more efficient and faster and better and... you get the point. My question is now... when would I not use a pointer? This is pretty overkill, but it demonstrates what I mean.
int x = 5, * pX = &x;
int y = 23, * pY = &y;
double delta = 5.4894, * pDelta = δ
//...Obviously, I'm not going to create a pointer per variable, but my question still stands: When would I not use a pointer? Googling some common usages yielded arrays and memory management which again is fine, but is that the only thing pointers should be used for?
Also, something I just thought of: Why are pointers more efficient than arrays when doing something like the following?
void test(int * p, int x) {
printf("%d", p[x]);
