Write a program to create a 3 by 3 array of integers and find the sum of each of its rows, columns and the left diagonal.

#include <stdio.h>

int main(void)
{
int arr[3][3], i, j, rsum, csum, diag;

for(i = 0 ; i < 3 ; i++)
{
printf("\nRow %d\n", i + 1);
for(j = 0 ; j < 3 ; j++)
{
printf("\tValue %d :", j + 1);
scanf("%d", &arr[i][j]);
}
}

diag = 0;
for(i = 0 ; i < 3 ; i++)
{
rsum = csum = 0;
for(j = 0 ; j < 3 ; j++)
{
rsum += arr[i][j];
csum += arr[j][i];
if(i == j) diag += arr[i][j];
}
printf("\nSum of row %d is %d", i + 1, rsum);
printf("\nSum of column %d is %d", i + 1, csum);
}

printf("\nSum of left diagonal is %d\n", diag);


return 0;
}
