Good question.
Code:
#include <iostream>
#include <stdio.h>
using namespace std;

typedef struct A
{
    enum a{ red,blue,green}a;

}obj11;
obj11 obj1;
int main()
{
    obj1.a=A::red;
    //obj1.a=red;          // how to set variable ?
    cout<<"sizeof struct is n "<<sizeof(obj1)<<"\n";
    cout<<"obj1.a is "<<obj1.a<<"\n";
    if (obj1.a == A::red)   // here i want to use comparison with red  
        cout<<"Hi\n";
    else
        cout<<"bye\n";

    return 0;
}

Detailed Description
   template<typename _InputIterator>class std::__detail::_Scanner< _InputIterator >
       struct _Scanner. Scans an input range for regex tokens.

       The _Scanner class interprets the regular expression pattern in the input range passed to its constructor as a sequence of parse tokens
       passed to the regular expression compiler. The sequence of tokens provided depends on the flag settings passed to the constructor:
       different regular expression grammars will interpret the same input pattern in syntactically different ways.

Member Enumeration Documentation

       Token types returned from the scanner.
