How come this code
std::map <std::string , int> m;
m["a"]=1;
compiles with (I’m using MSVC 2010)
#include <string>
but not with
#include <string.h>
?
<string.h>contains old functions likestrcpy,strlenfor C style null-terminated strings.<string>primarily contains thestd::string,std::wstringand other classes.
