How to print diagonal elements?

// Write a program to print diagonal elements of an array

int main()

{

int n,i,j,a[10][10];

printf("\n enter N:");

scanf("%d",&n);

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

{

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

{

printf("\n enter value at A[%d][%d]:",i,j);

scanf("%d",&a[i][j]);

}

}

printf("\n");

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

{

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

{

if(i==j)

printf(" %d",a[i][j]);

else

printf(" 0");

}

printf("\n");

}

}

Output:

enter N:3

 enter value at A[0][0]:1

 enter value at A[0][1]:2

 enter value at A[0][2]:3

 enter value at A[1][0]:4

 enter value at A[1][1]:5

 enter value at A[1][2]:6

 enter value at A[2][0]:7

 enter value at A[2][1]:8

 enter value at A[2][2]:9

 1 0 0

 0 5 0

 0 0 9
