Why am I getting string does not name a type Error?
Your using declaration is in game.cpp , not game.h where you actually declare string variables. You intended to put using namespace std; into the header, above the lines that use string , which would let those lines find the string type defined in the std namespace.
As others have pointed out, this is not good practice in headers — everyone who includes that header will also involuntarily hit the using line and import std into their namespace; the right solution is to change those lines to use std::string instead
‘string’ does not name a type

Change “string” to “std::string”
Most likely you did not mean to comment out line 12.
Also, what your professor told you only applies when you have optimizations on – in debug mode (no optimizations) it does not apply.
‘string’ does not name a type
OK, I’ve seen this error explained at least 100 times on the net. But in every case, it seems to be an error of #including instead of or metioning string instead of std::string. But, I’ve done all those things. And it still does not work.
By way of background: I am a LONG time newbie C++ programmer (meaning that I write code in spurts and then not at all for several years, which means that whenever I advance beyond newbie status, I slide back after time). I have also traditionally been coding using the old Borland compiler (which works, even if it is ancient, but I like the IDE). I have now been trying to come into the 21st century by using gnu c++ (g++ and mingw). The code problem that I am presenting compiles using the Borland compiler, but gives me the error message only when I try to compile with g++.
The problem code:
#ifndef ERRORHANDLER_H #define ERRORHANDLER_H #define DOS #include #include #include #include #include #include class ErrorReport { private: std::string logfilename; public: void set (const std::string name) {logfilename=name;}; std::string file() const {return logfilename;}; std::string GetNow() const { std::string now; char date [10]; _strdate(date); char time [10]; _strtime(time); now= date; now+= ” “; now+= time; now+= ” “; return now; }; . . .
You can see I use std::string and have this header protected with an #ifndef envelope. I am not using namespace in the header, which people tell me is a bad thing to do.
So, any suggestions??
Thanks for your time.

How to use string as type in header file in C++
I wanna use string as a type in my class header file, but even with and without the string lib, it shows me: error: ‘string’ does not name a type How can I use string in the header?
Caused by the “error string in namespace std does not name a type” error
struct sales_data { std::string bookNo; std::string bookName; unsigned int count; double price; }; int main() { return 0; }
A weird thing happened when I was learning c++ today: when compiling the following code, the compiler displayed an error:error: ‘string’ in namespace ‘std’ does not name a typeThe procedure is as follows:
obviously there is a #include< string>
However, if you modify the code as shown below, you will also compile successfully.
The modified code is as follows:
#include struct sales_data { std::string bookNo; std::string bookName; unsigned int count; double price; }; int main() { return 0; }
what is the reason for this?
After Google, at http://www.cplusplus.com/ query to the ios libraries and other libraries relationship is as follows:
As you can see from the figure above, the StringStream library has been declared in the IoStream library and includes some of the string functionality. So that’s what happened.
Code is broken with gcc 10.1 in src/configuration.cpp · Issue #165 · ColinPitrat/caprice32
