c++ when to put method out side the class
- by user63898
i saw that some times in c++ applications using only namespace declarations with header and source file like this :
#ifndef _UT_
#define _UT_
#include <string>
#include <windows.h>
namespace UT
{
void setRootPath(char* program_path, char* file_path);
char * ConvertStringToCharP(std::string str);
};
#endif
//and then in UT.cpp
#include "UT.h"
namespace UT
{
char * ConvertStringToCharP(std::string str)
{
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0';
return writable;
}
void setRootPath(char* program_path, char* file_path)
{
//...
}
}
is it better then defining classic class with static methods?
or just simple class ?
dose this method has something better for the compiler linker ?
the methods in this namespace are called allot of times .
