int search(int a[], int size, int k);

Implement a function that searches for a given value k in an array of integers. Do not assume the

values are in order. If the value is found, the function returns the index of the value in the array;

otherwise it returns -1. For example, for v = (-2, 4, 18, 6, -10) and k = 1, the function returns -1.

and for k = 4 it returns 1. A declaration of the function is given above. Include test code with

assertions.
