C program to find sum of all diagonal elements of a matrix | My CS Tutorial


In this tutorial we will learn  or discuss that how to write a c program code to find sum of diagonal elements of a matrix. In this program we will use arrays.

This c program code will find the sum of both left and right diagonal elements of a matrix.

In the first user will enter range of rows and columns of matrix. After it user enter the elements of first matrix.

After it compiler check and exicute the condition and logics and print given matrix and print the given matrix and print the sum of both or all diagonal elements of a matrix.

C PROGRAM CODE

#include<stdio.h>

#include<conio.h>

void main()

{

 int i,j,rows,col,diagonal_1=0,diagonal_2=0,m,n;

 int a[100][100];

 clrscr();

 printf("\n ENTER NUMBER OF ROWS:\n ");

 scanf("%d %d",&rows,&col);

 if(col==rows)

 {

  m=0;

  n=rows-1;

   //Taking input for matrix

 printf("\n ENTER ELEMENTS OF MATRIX:\n ");

  for(i=0;i<rows;i++)

  {

  for(j=0;j<col;j++)

  {

   scanf("%d",&a[i][j]);

  }

  }

  printf("\n THE GIVEN MATRIX IS:\n ");

  

  for(i=0;i<rows;i++)

  {

  for(j=0;j<col;j++)

  {

   printf("%d\t",a[i][j]);

  }

  printf("\n ");

  }

  for(i=0;i<rows;i++)

  {

   diagonal_1+=a[i][i];

   diagonal_2+=a[m][n];

   m++;

   n--;

  }

  

  printf("\n SUM OF FIRST DIAGONAL IS:\n %d",diagonal_1);

  printf("\n SUM OF ANOTHER DIAGONAL IS:\n %d",diagonal_2);

}

 else

 {

  printf("\n NOT POSSIBLE.......\n ");

 }

getch();

}
