An array is a collection of items stored at contiguous memory locations. In this article, we will see how to insert an element in an array in C.
Given an array arr of size n, this article tells how to insert an element x in this array arr at a specific position pos.
Here’s how to do it.
- First get the element to be inserted, say x
- Then get the position at which this element is to be inserted, say pos
- Then shift the array elements from this position to one position forward, and do this for all the other elements next to pos.
- Insert the element x now at the position pos, as this is now empty.
Below is the implementation of the above approach:
1 2 3 4 5 6 7 8 9 10 1 2 3 4 50 5 6 7 8 9 10
