Question

I came across a piece of code which is as below

qsort(array, 10, sizeof(int), sort);

Here sort is again a function. But I was always under the impression that any function which is called should have () after the function name or was I missing something.

I just wanted to know how will this work and what are the differences in calling functions like these. Thanks!

Answer 1

qsort(array, 10, sizeof(int), sort);

this passes a pointer to the function “sort” so that the function “qsort” can call this function.
