- In C Programming: You will need all the functions from the previous assignment, as well as the structure course:• Department (string, 15 characters)• Course number (integer, 4 digits, leading 0 if necessary)• Course title (string, 30 characters)• Credits (short, 1 digit) Write a function saveAllCoursesText() which receives an array of course pointers and the array’s size, then outputs the content of the array in text format to a file named “courses.txt”.• Save the entire structure on 1 line (all the members of the structure should be saved in 1 fprintf() command)C++ need help with part d to g only Assume the Product structure is declared as follows: struct Product { string description; // Product description int partNum; // Part number double cost; // Product cost }; (c) Declare a dynamic array of Products of size 5 and name it ”items”. Then initilize it with user input values. (d) Write a print function (not as a member of the struct) and pass a pointer to the pointer that points to the array (double pointer) and print all the items of the array in that function. (e) Define a max function (not as a member of the struct) that gets an array of items as an input and returns a pointer to the max element of the array. (f) Declare a 3 by 3 two dimensional dynamic array and populate it. (g) Define an output function that takes a stream object and a pointer to a 2D array as arguments and outputs data members of objects in format of 3*3 table into the given stream. Test your function both with an output file…Solution by C++
