C Program to read a matrix and find sum, product of all elements of two dimensional (matrix) array

This program will read a matrix and prints sum and product of all elements of the two dimensional array.

C program to read a matrix and find sum, product of all elements of matrix

#include <stdio.h>

#define MAXROW 10
#define MAXCOL 10

int main() {
  int matrix[MAXROW][MAXCOL];
  int i, j, r, c;
  int sum, product;

  printf("Enter number of Rows :");
  scanf("%d", &r);
  printf("Enter number of Cols :");
  scanf("%d", &c);

  printf("\nEnter matrix elements :\n");
  for (i = 0; i < r; i++) {
    for (j = 0; j < c; j++) {
      printf("Enter element [%d,%d] : ", i + 1, j + 1);
      scanf("%d", &matrix[i][j]);
    }
  }

  /*sum and product of all elements*/
  /*initializing sun and product variables*/
  sum = 0;
  product = 1;
  for (i = 0; i < r; i++) {
    for (j = 0; j < c; j++) {
      sum += matrix[i][j];
      product *= matrix[i][j];
    }
  }

  printf("\nSUM of all elements : %d \nProduct of all elements :%d", sum,
         product);
  return 0;
}

Output

Enter number of Rows :3 
Enter number of Cols :3 

Enter matrix elements : 
Enter element [1,1] : 1 
Enter element [1,2] : 1 
Enter element [1,3] : 1 
Enter element [2,1] : 2 
Enter element [2,2] : 2 
Enter element [2,3] : 2 
Enter element [3,1] : 3 
Enter element [3,2] : 3 
Enter element [3,3] : 3 

SUM of all elements : 18 
Product of all elements :216
