Hi friends,
The derived class cannot access the base class's variables in my program. You can have a look at my code, I am actually using class templates.
#include <iostream>
using namespace std;
template <class T>
class Sum
{
friend void Check(Sum &s, T a, T b)
{
T x,... (2 Replies)
Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

MONGO(3) 1 MONGO(3)The Mongo class [deprecated]
INTRODUCTION
A connection between PHP and MongoDB.
This class extends MongoClient and provides access to several deprecated methods.
For backwards compatibility, it also defaults the "w" option of its constructor argument to 0, which does not require write operations to
be acknowledged by the server. See MongoClient.__construct(3) for more information.
Warning
This class has been DEPRECATED as of version 1.3.0. Relying on this feature is highly discouraged. Please use MongoClient instead.
