In C language, also it would be great if you add comments.

1. Write a C program that finds the index of the first element of an input array that contains the value zero, starting from position pos. As part of the solution, write and call the function findZero () with the following prototype. n is the size of the array. If no element of the array from position pos to the end of the array contains the value zero, then the function should return -1. Name your program find0.c. int findZero (int a[], int n, int pos); Example input/output #1: Enter the length of the array 1: 5 Enter the elements of the array: 80 0 3 9 Enter the start position (index) for the searching: 0 Output:1 Example input/output #2: Enter the length of the array 1: 5 Enter the elements of the array:840 3 9 Enter the start position (index) for the searching: 3 Output: -1 Example input/output #3: Enter the length of the array l: 5 Enter the elements of the array: 8 4 0 39 Enter the start position (index) for the searching: 1 Output: 2 Example input/output #4: Enter the length of the array 1: 5 Enter the elements of the array: 8 4 2 3 9 Enter the start position (index) for the searching: 1 Output: -1
