Write a function record * fileSearch(FILE * f, int id) in C that searches for a student’s record (id, name, gpa) in a file using id. The function receives a FILE pointer and id and returns the record that matches the id. If the record is not found, return NULL. IDs are unique. Assume the file is already opened for reading The following structure is used to store the student records. struct rec{ int id; char name; float gpa;}; typedef struct rec record; Examples: Consider the following space delimited file called students.txt. 101 John 3.5102 Alice 3.8103 Bob 3.2104 Carol 3.9 FILE * f = fopen(“students.txt”, “r”); fileSearch(f, 101) ⟹ // a pointer to a structure with the following record is returnedfileSearch(f, 105) ⟹ NULL
