Determinant of 2x2 Matrix Program Code

#include <stdio.h>
int main() {
    int matrix[2][2] = {{1, 2}, {3, 4}};
    int det;
    
    // For 2x2 matrix: determinant = ad - bc
    // Where matrix = |a b|
    //               |c d|
    det = matrix[0][0] * matrix[1][1] - matrix[0][1] * matrix[1][0];
    
    printf("Determinant = %d\n", det);
    return 0;
}
