Q. Determinent of 2X2 matrix ?

THE OUTPUT WOULD BE

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