[C++] Program Penghitung Determinan Matriks Ordo 2x2 dengan C++

Pada saat SMA tentunya anda sudah pernah membahas tentang determinan matriks ini kan. Langsung saja kita terapkan kedalam pemrograman C++. Berikut adalah syntax dari determinan matriks berordo 2x2.

//Determinan Matriks 2x2
#include <iostream.h>
#include <conio.h>

#define Nmaks 3

void main()
{
 typedef matriks[Nmaks][Nmaks];
 int i,j,determinan;
 matriks A;
 char answer;

 do
 {
  clrscr();
  cout<<"DETERMINAN MATRIKS A : "<<endl<<endl;
 cout<<"Masukkan Nilai Matriks A : "<<endl;
 for(i=1;i<=2;i++)
 {
  for(j=1;j<=2;j++)
  {
   cout<<"A["<<i<<","<<j<<"] = ";
   cin>>A[i][j];
  }
 }

 clrscr();
 cout<<endl;
 //Proses Mencari Determinan Matriks A

 determinan = (A[1][1] * A[2][2]) - (A[2][1] * A[1][2]);

 clrscr();
 //Output Matriks A
 gotoxy(1,5);
 cout<<"A = ";
 for(i=1;i<=2;i++)
 {
  for(j=1;j<=2;j++)
  {
   gotoxy(2+4*j,2+2*i);
   cout<<A[i][j];
  }
 }
            
 gotoxy(1,8);
 cout<<"Determinan Matriks A = "<<determinan;
 cout<<endl;

 getch();
 clrscr();
 cout<<"== PROGRAM SELESAI =="<<endl<<endl;
 cout<<"Mau Melakukan Perhitungan Lagi?? [Y/T] "; cin>>answer;
 }
 while ((answer == 'y') || (answer == 'Y'));
}
