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
