Can someone explain how to append an element to an array in C programming?

Question

If I want to append a number to an array initialized to int, how can I do that?

int arr[10] = {0, 5, 3, 64};
arr[] += 5; //Is this it?, it\'s not working for me.         


        

Answer 1

You can have a counter (freePosition), which will track the next free place in an array of size n.
