Question

A. Consider “inclass2.h” header file. Define a structure which can hold the following student information: id, first name, last name, and gpa. Use appropriate header file guards. ( Max size of first and last name is 20, id is 7 and gpa is double).

B. Consider an array of student struct with the MAX_SIZE 10 and a first name. These will be provided as an input to your function. Write a function/method that using the given inputs prints out the ID for all the students with the same first name.

INPUTS: The struct array should be declared and initialized in the main function. The following students information should be used to initialize the first 5 elements of the array Mary Robin aaa111 4.0

Ada Thorne bbb222 3.9

Mary Gray ccc333 3.8

Arthur Eden ddd444 3.7

Mary Aslani eee555 3.6

A variable should be declared and initialized with the name “Mary” in the main and should be provided to the function in part B of the question as one of the inputs ( to print out the id of the students with the same first name).

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
