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
