Write a C program to accept the elements of a 3 x 3 matrix and find its sum of the major diagonal elements The program should print the given matrix along with its sum of the major diagonal elements?

#include <stdio.h>

#include <conio.h>

void main() {

int d[3][3] = { 1, 2, 6, 3, 8, 5, 5, 6, 7 };

int k = 0, j = 0;

int sum1 = 0, sum2 = 0;

for (j = 0; j < 3; j++) {

for (k = 0; k < 3; k++)

printf(" %3d", d[j][k]);

printf("\n");

}

for (j = 0; j < 3; j++) {

sum1 = sum1 + d[j][j];

}

k = 3 - 1;

for (j = 0; j < 3; j++) {

if (k >= 0) {

sum2 = sum2 + d[j][k];

k--;

}

}

printf("Sum of First diagonal= %d\n", sum1);

printf("Sum of Second diagonal= %d", sum2);

getch();
