write c program for Question 3

Write the following function int search(int a[], int n, int key, int **loc); a is an array to be searched, n is the number of elements in the array, key is the search key, and loc is a pointer to the first location of the search key in array a (if found) or NULL otherwise. The function returns 1 if key is found in a, and returns 0 otherwise. Write a main() and test it. Write a function to convert a string of 32 '1' and '0's in 2's complement form to a 32 bit signed integer: int bits2Integer(char bitString(]); The bit string is stored in the bitString[] argument in "natural" form, i.e., the MSB is on the left side and LSB on the right
