Write a function named count_matches that accepts a string to match (as char *), an array of strings (as char*[]), and the size of the array, and returns the number of strings in the array that have contain the string to match as a substring. For example, if strs is defined as char * strs[] = {"rainbow", "sunshine", "bowtie", "cow", "ow", "happy"};, then the call count_matches("ow", strs, 6) returns 4. The empty string is a substring of any string. You may assume that the size argument correctly represents the size of the array, and that the match string is not NULL.

Function: Write a C function as described, not a complete program.
