#include <string.h> // string
class Staff_member {
string nm;
public:
Staff_member(const string& name) : nm(name) {}
Staff_member(const Staff_member& x) : nm(x.nm) {}
~Staff_member() {}
Staff_member& operator=(const Staff_member& x);
const string& get_name() const { return nm; }
void set_name(const string& name) { nm = name; }
};
int main() {
Staff_member staff;
}
set up a project as win32 console application, then compile the above file, get a lot of error as follows. the string.h is in the devstudio/vc/include directory and is included into the project, but why the string cannot be found(error C2501: 'string' : missing decl-specifiers
)?
