```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…

3. Smart Numbers language C++ G autocomplete.ready O 1 > #include A number is called a smart number if it's digits can be partitioned into two sets such that the sum of the digits in both sets are equal. Example: 37965 is a smart number as 3+7+5 = 9 +6 . Similarly 52139 is also a smart number as 5+2+3 = 9 10 11 * Complete the 'findCount0fSmartNumbers' function below. 12 * The function is expected to return an INTEGER. * The function accepts following parameters: 1. INTEGER A * 2. INTEGERB 13 9+1. 14 137, 328 are not smart numbers. 15 16 Your task is to find all the smart numbers in the 17 */ 18 inclusive range [A,B] . 19 int findCountofSmartNumbers(int A, int B) { 20 21 } Input 22 23 > int main()--- You will be given two integers A, B. You need to complete the function where the above integers will be given as an argument. Output Return the number of smart numbers in the inclusive range [A,B].

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…
