Penggunaan While, Do while, For

Alhamdullilah tugas 6 tentang pengulangan menggunakan while, do while dan for dapat terselesaikan... scriptnya sbb :

#include <iostream>

using namespace std; //

int main()

{

  int x = 0;  // Deklarasi

 

  cout<<"==========While================";

  while ( x < 10 ) { // While x is less than 10

    cout<< x <<endl;

    x++;             // Update x so the condition can be met eventually

  }

  cout<<"===============================";

  cout<<"\n";

 cout<<"=========Do while===============";

  int A;

  A = 0;

  do {

    // "Hello, world!" akan dicetak 1x dulu

       cout<<"Hello, world!"<<endl;

         

  } while ( A != 0 );// akan melakukan perulangan tak terbatas jika nilai A tidak 0

  cout<<"===============================";

  cout<<"\n";

 

 cout<<"========= Do while ===============";

long pass, input ;

pass=12345;

do{

    cout<<"masukan password yg benar; ";

    cin>>input;

}while (input!=pass);

cout<<"password benar\n";

cout<<"terima kasih telah mencoba program ini......."<<endl;

cout<<"==============================================";

cout<<"\n";

cout<<"========= For ===============";

int C,D;

cout << "PENGULANGAN MENAIK" << endl;

for (C=0; C<4; C++) {

       cout << C+1 << endl;

 }

cout << '\n';

cout << "PENGULANGAN MENURUN" << endl;

 for (D=4; D>0; D--)

 {

 cout << D << endl;

 }

 cout<<"==============================";

 cout<<"\n";

cout<<"========= For Bersarang ===============";

 for (int j=1; j<=4; j++) {;

       for (int k=1; k<=j; k++) {;

       cout << k*j <<' ';

       }

 cout << '\n';

 }

cout<<"==============================";

 system("pause");

return 0;

}
