Contoh: Kode Sumber untuk Menambahkan Dua Bilangan Kompleks

// Complex numbers are entered by the user

#include 
using namespace std;

typedef struct complex
{
    float real;
    float imag;
} complexNumber;

complexNumber addComplexNumbers(complex, complex);

int main()
{
    complexNumber n1, n2, temporaryNumber;
    char signOfImag;

    cout << "For 1st complex number," << endl;
    cout << "Enter real and imaginary parts respectively:" << endl;
    cin >> n1.real >> n1.imag;

    cout << endl << "For 2nd complex number," << endl;
    cout << "Enter real and imaginary parts respectively:" << endl;
    cin >> n2.real >> n2.imag;

    signOfImag = (temporaryNumber.imag > 0) ? '+' : '-';
    temporaryNumber.imag = (temporaryNumber.imag > 0) ? temporaryNumber.imag : -temporaryNumber.imag; 

    temporaryNumber = addComplexNumbers(n1, n2);    
    cout << "Sum = "  << temporaryNumber.real << temporaryNumber.imag << "i";
    return 0;
}

complexNumber addComplexNumbers(complex n1,complex n2)
{
      complex temp;
      temp.real = n1.real+n2.real;
      temp.imag = n1.imag+n2.imag;
      return(temp);
}

Keluaran

Enter real and imaginary parts respectively:
3.4
5.5

For 2nd complex number,
Enter real and imaginary parts respectively:
-4.5
-9.5
Sum = -1.1-4i

Dalam masalah ini, dua bilangan kompleks yang dimasukkan oleh pengguna disimpan dalam struktur n1 dan n2.

Kedua struktur ini diteruskan ke addComplexNumbers() fungsi yang menghitung jumlah dan mengembalikan hasilnya ke main() fungsi.

Akhirnya, jumlah ditampilkan dari main() fungsi.
