Program C++ mencari bilangan terbesar dari 3 bilangan bulat

Algoritma :

Deklarasi

a,b      : integer

Deskripsi

    if ( a > b ) && ( a > c )

       then

              write(a)

else if (b > a) && (b > c)

then

              write(b)

else

then

              write(c)

endif

Berikut programnya :

#include <iostream.h>

#include <conio.h>

class terbesar{

friend istream& operator >> (istream&, terbesar&);

friend ostream& operator << (ostream&, const terbesar&);

public:

terbesar();

void bandingkan(){

     if ((a > b) && (a > c))

        cout<< " Bilangan terbesar : "<<a;

     else if ((b > a) && (b > c))

        cout<< " Bilangan terbesar : "<<b;

            else

                cout<< " Bilangan terbesar : "<<c<<endl;

};

private:

     int a,b,c;

};

terbesar::terbesar(){

cout << "menentukan bilangan terbesar dari yang diinputkan\n" << endl;

}

istream& operator >>(istream& cin, terbesar& masukan){

     cout<<"masukan bilangan pertama : ";

     cin>>masukan.a;

     cout<<"masukan bilangan kedua : ";

     cin>>masukan.b;

     cout<<"masukan bilangan ketiga : ";

     cin>>masukan.c;

     cout<<endl;

return cin;

}

ostream& operator << (ostream& out, const terbesar& keluaran){

     out<< " terima kasih "<<endl;

return out;

}

void main(){

terbesar bilangan;

cin>>bilangan;

bilangan.bandingkan();

cout<<bilangan;

getch();

}

Explanation:
The program above is the program used to search for the greatest number of 3 numbers are entered. This program uses the selection or conditional if ... else. Which process is if ((a> b) & & (a> c)) and will display a floating largest is a, then if ((b> a) & & (b> c)) will display the number of the largest is b but if not satisfy both these conditions it will display the greatest number is c.
