C Program to find the sum of the elements of a 2-D array.

    In this example, we will find the sum of the elements of a 2-D array allowing the user to enter the row size and column size according to their requiremnts. 

    Here in the output we have entered a row  size 3 and column size 3.

PROGRAM

#include<stdio.h>

#include<conio.h>

void main()

{

    int a[50][50],r,c,i,j,sum=0;

    printf("Enter the row size and column size of the array :");

    scanf("%d%d",&r,&c);

    printf("Enter the elements of the array : ");

    for(i=0;i<r;i++)

    {

        for(j=0;j<c;j++)

        {

            scanf("%d",&a[i][j]);

        }

    }

    for(i=0;i<r;i++)

    {

        for(j=0;j<c;j++)

        {

            sum=sum+a[i][j];

        }

    }    

    printf("The sum of the elements of the array is = %d",sum);

    getch();

}

OUTPUT

Enter the row size and column size of the array :3

3

Enter the elements of the array : 12
