WRITE CODE USING C Language

A student ID of a university uses 15 digits student ID formatd, d2d3dad de dyded9d10d12d12d13d12d13 Example 9 7 8 0 1 3 2 1 3 0 8 OOO 6 The last digit d15 is a checksum, which is calculated from the other digits using the following formula: 10 - (d1+3d2+ d3 + 3d4 +d5 +3d6+d7+ 3d8 + d9 + 3d 10+d11 +3d12+d13+3d14)%10. If the checksum is 10, replace it with 0. 1. Write a function named readString that takes only an array of character as parameter named data, reads a string of size 13 from the user, and sore it the array data. The function should ask the user to enter a proper string of until the user enters a string of size 15 2. Write a function named checksum that takes only one input parameters str of type char* (null-terminated C strings of characters) and calculates and returns the check sum from the first 10 digits 3. Write the main function that Prints your full name and Student ID Define a proper variable to store a c-string Properly call the function readString to read a 15-digit student ID Displays valid student ID if digit 15 equals the checksum calculated in part2 or invalid otherwise 4. Add your name, your University ID number and section number as a comment at the beginning of this program. Sample Run
