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.

#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
