Question 2
Using the incomplete programming code given, complete the code using dynamic programming with memory function, to reproduce the results in the following Table 1. (C++)
#include<iostream>using namespace std;
// max knapsack capacity // *** WRITE YOUR CODE HERE ***// num of items // *** WRITE YOUR CODE HERE ***// weight of each item // *** WRITE YOUR CODE HERE ***// value of each item // *** WRITE YOUR CODE HERE ***// variable for dynamic programming matrix // *** WRITE YOUR CODE HERE ***
//==========================================// Dynamic programming function: recursive// =========================================
// ALGORITHM F(i,j) // int value // if F[i,j] is not filled yet (-1): // (start with j = W, i = n) // if capacity j < current item's weight w[i]: // value = recall F(i-1, j) // else: // we can include current item,…

Exercise 1: Memory Allocation in C
a) Write a C program which dynamically allocates memory to define an integer 5 x 5 matrix initialized to zero by using the calloc function. Do not forget to free the memory in the end of your program.
b) What happens if you attempt to print your matrix before and after freeing memory?
