C Program to Find Sum of Opposite Diagonal Elements in a Matrix

C program to find sum of opposite diagonal elements in a matrix; Through this tutorial, we will learn how to find sum of opposite diagonal elements in a matrix in c programs.

C Program to Find Sum of Opposite Diagonal Elements in a Matrix

/* C Program to find Sum of Opposite Diagonal Elements of a Matrix */

#include<stdio.h>

int main()
{
 	int i, j, rows, columns, a[10][10], Sum = 0;

 	printf("\n Please Enter Number of rows and columns : ");
 	scanf("%d %d", &i, &j);

 	printf("\n Please Enter the Matrix Elements \n");
 	for(rows = 0; rows < i; rows++)
  	{
   		for(columns = 0;columns < j;columns++)
    	{
      		scanf("%d", &a[rows][columns]);
    	}
  	}

 	for(rows = 0; rows < i; rows++)
  	{
  		for(columns = 0;columns < j; columns++)
  		{
  			if(rows + columns == ((i + 1) - 2))
  			       Sum = Sum + a[rows][columns];
		}
  	}

 	printf("\n The Sum of Opposite Diagonal Elements of a Matrix =  %d", Sum );

 	return 0;
}

The output of the above c program; as follows:

Please Enter Number of rows and columns : 3 3
Please Enter the Matrix Elements
1 2 3
4 5 6
7 8 9
The Sum of Opposite Diagonal Elements of a Matrix =  15
