Sep 5, 2018 · In C, we can use function pointers to avoid code redundancy. For example a simple qsort () function can be used to sort arrays in ascending order or descending or by any other order in case of array of structures. Not only this, with function pointers and void pointers, it is possible to use qsort for any data type. #include <stdio.h>

Function pointers in C can be used to perform object-oriented programming in C. For example, the following lines is written in C: String s1 = newString (); s1->set (s1, "hello"); Yes, the -> and the lack of a new operator is a dead give away, but it sure seems to imply that we're setting the text of some String class to be "hello".

In C programming, it is also possible to pass addresses as arguments to functions. To accept these addresses in the function definition, we can use pointers. It's because pointers are used to store addresses. Let's take an example: Example: Pass Addresses to Functions
