Q. Determinent of 3X3 matrix ?

THE OUTPUT WOULD BE

 
#include<stdio.h>
#include<conio.h>
  void main( )
  {    clrscr( );
        int a[3][3],j,i,d;
        for(i=1;i<=3;i++)
        { for(j=1;j<=3;j++)
          { printf("Enter an element:");
             scanf("%d",&a[i][j]);
          }
        }
        printf("\nMatrix element are given below\n");
        for(i=1;i<=3;i++)
        { for(j=1;j<=3;j++)
          { printf("\t%d",a[i][j]);
          }
          printf("\n");
        }
       d=a[1][1]*(a[2][2]*a[3][3]-a[2][3]*a[3][2])-a[1][2]*(a[2][1]*a[3][3]-a[3][1]*a[2][3])+a[1][3]*(a[2][1]*a[3][2]-a[2][2]*a[3][1]);
       printf("Determinant of matrix=%d",d);
       getch( );
}
