structure does not name a type in c++

Question

I get an issue while return type is structure

Example.h

class Example {
private:
    typedef struct connection_header {
        string url;
        string method;
    };

    static connection_header get_connection_header();
};

Example.cpp
connection_header Example::get_connection_header() {
    return NULL;
}

I am getting 'connection_header' does not name a type

may i know why is this error

Answer 1

You are using typedef without giving a name to the type. Just drop the typedef, it is not needed here:

struct connection_header {
    string url;
    string method;
};

Next, connection_header is declared inside of the Example class, so you need to fully qualify its name in the implementation when it is a return type:

Example::connection_header Example::get_connection_header()
