cant use goto or recursion or global variables along with scanf

Write a program that read the id, names, and marks for a number of students from the user. The program then displays a list of all the students and the average marks. This assignment will help you understand C pointers, characters, and strings. NOTE: do NOT use scanf in this assignment. . The program will REQ-1: in main function, read the total number of students from the user. Valid number of students is 1 to 10 When the number is valid, create three arrays for storing the id, the name, and the marks. Then call the following two functions. REQ-2: In a function, read id, name, and marks for student from the user, store them into the three arrays defined in the main function. Do not use structure here. Each record is given in a line of text, with id, name, and marks separated by a comma. Student id is a positive integer, name is any string that contains letters and spaces and mark is a positive double value not greater than 10. Validate the id and the marks, and read the line again if there is any errors in the data. REQ-3: In another function, print the list of students and the average mark. Student names are displayed in all. caps. Average mark is formatted to 2 decimals. --- Enter number of students (1-10): 33 = Enter number of students (1-10): -2 --- Enter number of students (1-10): 4 --- Enter id, name, and mark separated by comma.
