```cpp// Assume all libraries are includedvoid func(int a, int &b, int &c);// ------------------------------int main(){ int i = 5, j = 4, k = 3; func(i, j, k); func(j, i, k); cout << j << k << i << endl; return 0;}// ------------------------------void func(int a, int &b, int &c){ a = 2*c + b; b = c - a; c = a + 3*b;}// ------------------------------```This C++ code demonstrates a program using functions with reference parameters. In the `func` function, the parameters `b` and `c` are references, meaning changes to them will affect the original variables passed to the function.### How It Works:1. **Initialization:** - Variables `i`, `j`, and `k` are initialized to 5, 4, and 3 respectively.2. **First Function Call `func(i, j, k)`:** - `a` is set as `2*k + j`. - `b` is updated to `k - a`. - `c` is updated to `a + 3*b`.3. **Second Function Call `func(j, i, k)`:** - The values of `j`, `i`, and `k` are now passed to the function, modifying them again through similar calculations. 4. **Output:** - `cout << j << k << i << endl;` will output the values of `j`, `k`, and `i` after the function calls have been executed.This code highlights the usage of reference parameters in C++ and how they can be utilized to alter the values of the variables passed to the function.

in func variable a is taken by value but b and c are taken by reference. so, whatever changes made…

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…
