Array040

Input a matrix and determine whether it is symmetric matrix or not .

NB: A matrix is called a symmetric matrix when i, j th element is equal to j,i th element for all i and j .

#include <stdio.h>
#include <conio.h>
void main ( )
{
         int      n1[3][3], i, j, f = 0;
         clrscr ( );
         
         printf ("\n\t\t\t Enter numbers in a matrix");
         printf("\n\t\t\t____________________________\n");
         for ( i = 0; i < 3; i++ )
         {          
                     for ( j = 0; j < 3; j++)
                     {           
                                 printf("\n\t\t\t Position [%d] [%d]..:",i,j); scanf ("%d", &n1[i][ j] );
                     }
         }
         clrscr ( );
          
         printf("\n\n\n\n\t\t\t    Matrix\n\t\t\t______________\n\n\t\t\t");
