Tugas Dasar-Dasar Pemrograman - Kalkulator Sederhana

Coding:


#include <iostream>

using namespace std;

int main(){

int pilih_operator;
double A, B, hasil;

cout<<"--------------------------------------";
cout<<"\n---------KALKULATOR SEDERHANA---------";
cout<<"\n--------------------------------------";
cout<<"\n        1. Penjumlahan    [+]";
cout<<"\n        2. Pengurangan    [-]";
cout<<"\n        3. Perkalian         [x]";
cout<<"\n        4. Pembagian      [:]";
cout<<endl<<endl;
cout<<"Pilihan Operator (1/2/3/4) = ";
cin>>pilih_operator;

switch(pilih_operator){
case 1: cout<<"\n--PENJUMLAHAN"<<endl;
cout<<"  Masukkan nilai 1: ";
cin>>A;
cout<<"  Masukkan nilai 2: ";
cin>>B;
cout<<"  Hasil = "<<A+B<<endl;
break;

case 2: cout<<"\n--PENGURANGAN"<<endl;
cout<<"  Masukkan nilai 1: ";
cin>>A;
cout<<"  Masukkan nilai 2: ";
cin>>B;
cout<<"  Hasil = "<<A-B<<endl;
break;

case 3: cout<<"\n--PERKALIAN"<<endl;
cout<<"  Masukkan nilai 1: ";
cin>>A;
cout<<"  Masukkan nilai 2: ";
cin>>B;
cout<<"  Hasil = "<<A*B<<endl;
break;

case 4: cout<<"\n--PEMBAGIAN"<<endl;
cout<<"  Masukkan nilai 1: ";
cin>>A;
cout<<"  Masukkan nilai 2: ";
cin>>B;
cout<<"Hasil = "<<A/B<<endl;
break;

defult:
cout<<"\nOops, Anda salah memilih operator!!!";
}

cout<<endl<<endl<<endl;
cout<<"--------------------------------------\n";
system("PAUSE");
return 0;
}

Hasil:

1. Operator Hitung Penjumlahan

2. Operator Hitung Pengurangan

3. Operator Hitung Perkalian

4. Operator Hitung Pembagian
