How to delete element from array by pointers

Question

I want to delete n'th element from array and when I use for loop I want program to print all numbers by sequence except that n'th element. Ex. 4 7 6 2 9 5.

If I want to delete the 2nd element then after deleting I want to print 4 7 2 9 5 and I don't want to move every element to left.

Is it possible using free() or pointers?

Please explain me, I'm new in pointer programming.

No it's not possible without moving the elements in the array, an array doesn't have any "holes" in it. It's not even possible with an array allocated dynamically with e.g. malloc. Perhaps arrays is the wrong kind of data-structure whatever problem you want to solve? — Some programmer dude

When you mean delete, you mean equal to 0 or suppress the element or only not printing it ? — Umaiki

No, it is not possible if the data is a C array of integers, e.g.:

int array[10];

However, if you used another data structure, like a linked list, it is possible to remove an element without moving the rest.

You cannot just remove an element of an array using free() You have to opt for Data structures like Linked List in order to do such operations! https://www.geeksforgeeks.org/linked-list-set-3-deleting-node/ Try this !
