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 print diagonal elements of a Matrix which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C Program to print diagonal elements of a 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 Diagonals elements of a matrix are :: \n\n");
/*check condition to print diagonals, matrix must be square matrix*/
if(m==n)
{
/*print diagonals*/
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
if(i==j)
printf("\t%d", array1[i][j]); /*print elements*/
else
printf("\t"); /*print space*/
}
printf("\n\n"); /*after each row print new line*/
}
}
else
{
printf("\nMatrix is not a Square Matrix.");
}
return 0;
}
Output : :
/* C Program to print diagonal elements of a Matrix */
Enter no. of rows :: 3
Enter no. of cols :: 3
Enter values to the matrix ::
Enter a[0][0] value :: 1
Enter a[0][1] value :: 2
Enter a[0][2] value :: 3
Enter a[1][0] value :: 4
Enter a[1][1] value :: 5
Enter a[1][2] value :: 6
Enter a[2][0] value :: 7
Enter a[2][1] value :: 8
Enter a[2][2] value :: 9
