#include <iostream>
#include <windows.h>
#include <winnt.h>

using namespace std;

BOOL IsElevated( ) {
    BOOL fRet = FALSE;
    HANDLE hToken = NULL;
    DWORD Elevation;
    if( OpenProcessToken( GetCurrentProcess( ),TOKEN_QUERY,&hToken ) ) {
        typedef Elevation TOKEN_ELEVATION;
        DWORD cbSize = sizeof( TOKEN_ELEVATION );
        if( GetTokenInformation( hToken, TokenElevation, &Elevation, sizeof( Elevation ), &cbSize ) ) {
            fRet = Elevation.TokenIsElevated;
        }
    }
    if( hToken ) {
        CloseHandle( hToken );
    }
    return fRet;
}

int main()
{
    bool valor=IsElevated( );

    if(valor==true){
        cout << "Tienes permisos de administrador";
    }else{
        cout << "Eres un usuario corriente";
    }
    system("pause");
    return 0;
}

You can use typedef to give existing types a new name like typedef unsigned char uchar
However your Elevation is not a type but the name of a variable

DWORD Elevation;
typedef Elevation TOKEN_ELEVATION;

TOKEN_ELEVATION is a type. See:

https://msdn.microsoft.com/en-us/library/windows/desktop/bb530717(v=vs.85).aspx

Hence the type of Elevation shouldn't be DWORD but TOKEN_ELEVATION.

If there is a problem with TOKEN_ELEVATION see:
