Look at the code here:

if (pos != -1)
{
goto badsearch;
}

I think you meant:

if (pos == -1)

There are a lot of "bugs" in your code.
Frist, you miss the using namespace std; line before the main() function, so the compiler might not recognize cout and string.
You also missed a semicolon...

We won't do your homework. You should provide us some code so we can know you've at least tried.

#include<iostream>
#include<string>

using namespace std;

#define IS_STRING 1
#define IS_CHARACTER 2
#define IS_INTEGER 3
#define IS_FLOAT 4

private:

double raduis;

I think you swapped these two letters
