Calculate Sum of Primary diagonal of Matrix


Write a C Program To calculate Sum of Primary diagonal of Matrix. Here’s simple Program To calculate Sum of Primary diagonal of Matrix in C Programming Language.


What is Matrix ?


Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.

Two-dimensional Arrays : :

The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.

To declare a two-dimensional integer array of size [x][y], you would write something as follows −

  • type arrayName [ x ][ y ];

Where type can be any valid C data type and arrayName will be a valid C identifier.


Below is the source code for C Program To calculate Sum of Primary diagonal of Matrix which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C Program To calculate Sum of Primary diagonal of Matrix  */

#include<stdio.h>

int main()
{
    int array1[10][10],i,j,m,n,sum = 0;
    
    printf("Enter no. of rows :: ");
        scanf("%d", &m);
        printf("\nEnter no. of cols :: ");
        scanf("%d",&n);
        printf("\nEnter values to the matrix :: \n");
        for (i = 0; i < m; i++)
        {
            for (j = 0; j < n; j++)
            {
                 printf("\nEnter a[%d][%d] value :: ",i,j);
                 scanf("%d", &array1[i][j]);
        }
    }
    
    printf("\nThe given matrix is \n\n");
        for (i = 0; i < m; ++i)
        {
        for (j = 0; j < n; ++j)
        {
            printf("\t%d", array1[i][j]);
        }
        printf("\n\n");
    }
    
    for(i=0;i<m;i++)
    sum = sum + array1[i][i];
    printf("\nTHE SUM OF PRIMARY DIAGONAL OF MATRIX IS :: %d \n", sum);
  
   return 0;
}

Output : :
