#include<studio.h>
int main ( )

int a [2] [2], i, j ;
long determinant ;

printf("Enter the 4 elements of matrix:");
for(i=0;i<2;i++)
for(j=0;j<2;j++)
scanf("%d", &a[i][j]);

printf("\n The matrix is\n");
for(i=0;i<2;i++)

printf("\n");
for(j=0;j<2;j++)
printf("%d\t",a[i][j]);
}
determinant = a [0] [0] * a[1] [1]- a [1] [0] * a [0] [1];

printf( "\n Determinant of 2×2 matrix: %1d",determinant);

return 0;
}

output :

Enter the 4 elements of matrix: 4
8
3
9

The matrix is
4 8
3 9


Determinant of 2×2 matrix:12.
0
