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!
