Typedef of enum

[rhlgupta1383]

#include <iostream>

using namespace std;

int main(){
typedef enum { false, true} boolean;
boolean b = false;
cout<<b;
cin.get();
return 0;
}

The above code is giving error... pls help

You may not use keywords for enumerators. So this declaration

typedef enum { false, true} boolean;

is invalid because false and true are reserved keywords.

You could declare the enumeration the following way

typedef enum { FALSE, TRUE} boolean;
boolean b = FALSE;

Or if you want only to declare an alias for the type bool then you can write simply either

typedef bool boolean;
or

using boolean = bool;

You don't need to attempt that typedef either as bool, true and false are defined as you'd expect.
