Call the readFile() function to read the contents of the text file “numbers.txt” to the array and return the number of elements read to the array. 4. Call the writeToFile() function to write the names and valid students numbers and names and invalid student numbers to two separate text files.

Write a function called displayData() to receive the array and number of elements as parameters and display the names and student numbers of the students with a heading and neatly spaced.
Write a function, isValid(), which receives a number as parameter and determines whether the number is a valid student number or not. Use the following validity test to determine the validity of a student number: Student number: 20570856 sum = (2*8)+(0*7)+(5*6)+(7*5)+(0*4)+(8*3)+(5*2)+(6*1) result = sum%11 If the result equals 0, the number is a valid student number; if the result is not equal to 0, the number is an invalid student number. The function MUST use a loop to analyse the number by looking at each individual digit in the number. The function returns the Boolean value true (valid) or the Boolean value false (invalid) to the calling statement. Hint: Repeatedly use integer division (/) with 10 and the remainder after integer division (%) with 10 to isolate the individual digits of the number.
Write a function, writeToFiles(), which receives the array of Student structs and the number of elements in the array. If the student number is valid, the name and student number must be written to an output file, validNumbers.txt. If the student number is invalid, the name and student number must be written to an output file, invalidNumbers.txt. Display the number of valid and the number of invalid number. The function returns no value to the calling statement.
