Hi guys. I read about function pointers in C And everyone said that will make my program run slow. Is it true?

I made a program to check it. And I got the same results on both cases. (mesure the time.)

So, is it bad to use fuction pointer? Thanks in advance.

To response for some guys. I said 'run slow' for the time that I have compared on a loop. like this.

int end = 1000; int i = 0;

while (i < end) { fp = func; fp (); }

When you execute this, i got the same time if I execute this.

while (i < end) { func (); }

So I think that function pointer have no difference of time and it don't make a program run slow as many people said.
