    cin>>a;

    cout<<"pilih operator +,-,*,/ = ";

    cin>>aritmatika;

    cout<<"masukan nilai kedua = ";

    cin>>b;

   

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

    cout<< a << aritmatika <<b;

   

    if (aritmatika == '+'){

        hasil = a+b;

    }else if (aritmatika == '-'){

        hasil = a-b;

    }else if (aritmatika == '*'){

        hasil = a*b;

    }else if (aritmatika == '/'){

        hasil = a/b;

    }else{

        cout<<"operasi salah"<<endl;
