C++ Calculator Help

Hello I'm new to C++ and was working on making a simple calculator... What I want it to have is at least 1 loop, switch statement, 1 array with [10]... i don't need a menu just something that you can type the operation and number to add,sub,mult, and divide... i'd also like it to keep displaying the current value...........any help would be apreciated...

Thanks!!

Heres the basic code i have so far....

Code:

#include<iostream>
using namespace std;
int main()
{
  int a,b,res;
  char op;
  cout<<"Please Enter A Number and +,-,*,or/ then another Number-> ";
  while(cin>>a>>op>>b){
    switch(op){
    case'+':res = a  + b;
      break;
    case'-':res = a  - b;
      break;
    case'*':res = a * b;
      break;
    case'/':if(a == 0 || b ==0)
	cout<<"Error: division by zero: ";
      else
	res = a / b;
      break;
    default: cout<<"Error: "<<op<<" is not accepted\n";
    }
    cout<<res<<": ";
  }
  return 0;
}

Its just not what i want though... I want an array[10] and my switch and loop to be right... which i dont' think it is..

Thanks!

It's only division by zero if b == 0.
