Question

write a program to input and store integer elements in a double dimensional array of size 3*3and find the sum of the elements in the left diagonal.example:-1 3 5 down 4 6 8 down 9 2 4.output:- sum of the left diagonal elements in the left diagonal elements=(1+6+4)=11​

Answer 1

Explanation:

in c programming

#include<stdio.h>

int main()

{

int i,j,r,c,a[10][10],sum=0;

scanf("%d %d",&i,&j);

for(r=0;r<i;r++)

{

for(c=0;c<j;c++)

{

scanf("%d",&a[r][c]);

}

}

for(r=0;r<i;r++)

{

sum=sum+a[r][r];

}

printf("sum of digonal elements is %d",sum);

}
