rmc/rmc.h:18: error: ISO C++ forbids declaration of `rules' with no type

Code:

---

#ifndef _RMC_H
#define        _RMC_H


#include <cstdio>
#include <string>
#include <vector>

class RMC {
    std::vector <std::string> rules;
    rules.push_back("This is a string");

};



#endif        /* _RMC_H */

---

I have worked on this for a while. It works when I put it in the main() function, but never in classes. Why? Any help sure is appreciated!

This statement should be placed in a function:

Code:

---

rules.push_back("This is a string");

---

It does not belong in a class definition (unless it is within a function) because it is not some declaration of a member variable, member function, etc.
