simple calculator

[DrInvisible 4]

I´m new in C++ so at the time I can´t create hacks or other nice things, but I learn and so I post some projects (Info: i learn with a book, no c&p )

This calculator calculate -> +,-,*,/

 

Sourcecode

#include <iostream>
#include <string>

using namespace std;
int main()
{
   double zahl1;
   double zahl2;
   char op;

   cout << endl << "Th3Rock"
        << endl << endl;
   cout << "Insert your Calculation and press Enter"
        << endl << endl;

   cin >> zahl1 >> op >> zahl2;

   switch (op)
   {
          case '+': cout << "= " << (zahl1 + zahl2) << endl;
                    break;
          case '-': cout << "= " << (zahl1 - zahl2) << endl;
                    break;
          case '/': cout << "= " << (zahl1 / zahl2) << endl;
                    break;
          case '*': cout << "= " << (zahl1 * zahl2) << endl;
                    break;
          default: cout << "Only +,-,* and / " << endl;
          }
          system("PAUSE");
          return 0;
          }

mh... u could use a loop, so u needn´t to reopen the prog, if u want to calculate something...
