Ok, i used a couple C++ programming books to help me make a calc. A friend of mine suggest that i make a "Would you like to solve another problem? (Y/N)" and Y loops back and N closes the program. here is my code:

```
#include <iostream.h>
int Add(int num1, int num2);
int Subtract(int num1, int num2);
int Multiply(int num1, int num2);
int Divide(int num1, int num2);
// The main procedure. When the program starts, it goes here.
int main(int argc, char *argv[])
{
int x, y; // Integers 'x' and 'y' - The two numbers to add
int doNum; // Integer 'doNum' - Add, Subtract, Multiply, or Divide?
int b=1; // Integer 'b' - App runs while b = 1
while(b==1)
{
cout<<"Please enter two numbers with a space inbetween.press enter: ";
cin>>x>>y;
cout<<"Pleas press the number of what you want to do, press enter: "<<endl;
cout<<"1. Add"<<endl;
cout<<"2. Subtract"<<endl;
cout<<"3. Multiply"<<endl;
cout<<"4. Divide"<<endl;
cin>>doNum;
switch (doNum)
{
case 1:
cout<<x<<" plus "<<y<<" = "<<Add(x, y)<<endl;
break;
case 2:
cout<<x<<" minus "<<y<<" = "<<Subtract(x, y)<<endl;
break;
case 3:
cout<<x<<" multiplied by "<<y<<" = "<<Multiply(x, y)<<endl;
break;
case 4:
cout<<x<<" divided by "<<y<<" = "<<Divide(x, y)<<endl;
break;
} //switch
} //while
return 0;
}
// This function adds two variables
int Add(int num1, int num2)
{
return num1+num2;
}
// This function subtracts two variables
int Subtract(int num1, int num2)
{
return num1-num2;
}
// This function multiplies two variables
int Multiply(int num1, int num2)
{
return num1*num2;
}
// This function divides the first variable by the second
int Divide(int num1, int num2)
{
return num1/num2;
}
```
