C program to print diagonal elements of matrix

Output:

Enter the elements of matrix:
1 2 3
4 5 6
7 8 9
The diagonal elements of the matrix are:
1 5 9

Implementation:

#include <stdio.h> #define r 3 // set the row size here #define c 3 // set the column size here int main(void) { int a[r][c]; int i,j; printf("Enter the elements of matrix:\n"); for(i=0;i<r;i++) { for(j=0;j<c;j++) { scanf("%d",&a[i][j]); } } /* printing the diagonal elements of the matrix */ printf("The diagonal elements of the matrix are:\n"); for(i=0,j=0;i<r||j<c;i++,j++) { printf("%d ",a[i][j]); } return 0; }
