Write a c++ programs for malloc() and calloc().

 #include <iostream>

#include <cstdlib>

int main() {

  // Allocate memory for an array of 10 integers using malloc()

  int *arr = (int*)malloc(10 * sizeof(int));

  // Check if the memory was successfully allocated

  if (arr == NULL) {

    std::cerr << "Error allocating memory" << std::endl;

    return 1;

  }

  // Initialize the elements of the array to 0

  for (int i = 0; i < 10; i++) {

    arr[i] = 0;

  }

  // Print the elements of the array

  std::cout << "Elements of the array allocated with malloc(): ";

  for (int i = 0; i < 10; i++) {

    std::cout << arr[i] << " ";

  }

  std::cout << std::endl;

  // Deallocate the memory

  free(arr);

  // Allocate memory for an array of 10 integers using calloc()

  int *arr2 = (int*)calloc(10, sizeof(int));

  // Check if the memory was successfully allocated

  if (arr2 == NULL) {

    std::cerr << "Error allocating memory" << std::endl;
