MEMBUAT POLA SEGITIGA

Listing program: 

#include <iostream>

using namespace std;

 

int main(){

                int n;

                cout<<"masukkan panjang pola: "; cin>>n;

               

                cout<<"pola 1 \n";

                for (int i=1; i <=n; i++){

                    for (int j=1; j <=i; j++){

                                                cout<<"*";

                                }

                cout<<endl;

                }

               

                cout<<"pola 2 \n";

                for (int i=1; i <=n; i++){

                    for (int j=n; j >=i; j--){

                                cout<<"*";

                                }

                    cout<<endl;

                }

               

                cout<<"pola 3 \n";

                for (int i=1; i<=n; i++){

                                for (int j=1; j<i; j++){

                                                cout<<" ";

                                }

                                for (int k=n; k>=i;k--){

MEMBUAT PROGRAM C++ KALKULATOR

Listing program:

#include <iostream>

using namespace std;

 

int main()

{

 float a, b, hasil;

 char aritmatika;

 

 cout << "Selamat datang di program kalkulator\n\n";

 cout << "Masukan angka pertama: ";

 cin >> a;

 cout << "Masukan angka kedua: ";

 cin >> b;

 cout << "Pilih operator [+,-,/,*] : ";

 cin >> aritmatika;

 

 switch (aritmatika)

 {

  case '+':

   hasil = a + b;

   cout << "Hasil Perhitungan: \n";

   cout << a << aritmatika << b << " = " << hasil << endl;

   break;

  case '-':

   hasil = a - b;

   cout << "Hasil Perhitungan: \n";

   cout << a << aritmatika << b << " = " << hasil << endl;

   break;

  case '*':

   hasil = a * b;

   cout << "Hasil Perhitungan: \n";

   cout << a << aritmatika << b << " = " << hasil << endl;

   break;

  case '/':

   hasil = a / b;

   cout << "Hasil Perhitungan: \n";

   cout << a << aritmatika << b << " = " << hasil << endl;

   break;

  default:

   cout << "Operator salah\n";

 }

 

 

  cin.get();

  cin.get();

  return 0;

}
