CODE

👇

  1. #include<stdio.h>
  2. #include<conio.h>

  4. void main()
  5. {
  6.     int a[2][2], i, j;
  7.     long determinant;

  9.     printf("Enter the 4 elements of matrix  :\n");
  10.     for (i = 0; i < 2; i++)
  11.     {
  12.         for (j = 0; j < 2; j++)
  13.         {
  14.             scanf("%d", &a[i][j]);

  25.         }
  26.     }

  28.     determinant = a[0][0] * a[1][1] - a[1][0] * a[0][1];

  30.     printf("\nDeterminant of 2X2 matrix: %ld", determinant);
