How do you add to an array in C?

Approach:

1. First get the element to be inserted, say x.
2. Then get the position at which this element is to be inserted, say pos.
3. Then shift the array elements from this position to one position forward, and do this for all the other elements next to pos.
4. Insert the element x now at the position pos, as this is now empty.

Why is array insertion?

6 Answers. O(1) accurately describes inserting at the end of the array. However, if you’re inserting into the middle of an array, you have to shift all the elements after that element, so the complexity for insertion in that case is O(n) for arrays.

Why insertion and deletion is difficult in array?

Arrays have slow insertion and deletion times. This implies that insertion time for arrays is Big O of n (O(n)) as n elements must be shifted. However, inserting and deleting form the end of an array is O(1).

How do you add the sum of an array?

Algorithm

1. Declare and initialize an array.
2. The variable sum will be used to calculate the sum of the elements. Initialize it to 0.
3. Loop through the array and add each element of array to variable sum as sum = sum + arr[i].
