Suppose I have the following class in a header file
//tray.h
#include <vector>
#include "Eggs.h"
#ifndef TRAY_H
#define TRAY_H
class Tray{
std::vector<Eggs> dozen;
public:
Tray();
~Tray();
std::vector<Eggs> getTray() const;
};
#endif
And the following class file
//tray.cpp
#include "Tray.h"
#include <string>
Tray::Tray(){
}
Tray::~Tray(){
}
How do I initialize the vector dozen in the class?
You should use the initialization list, which is something like this in general:
Foo::Foo() : member1(/* something */), member2() { };
And so, for a dozen eggs, you should use one of the constructors of vector class, such as this:
Tray::Tray() : dozen(12, Eggs()) { };
where "Eggs()" can be some other constructor call, I just used the default constructor there.
And for the destructor, you don't need anything, because the vector will be automatically destroyed.
Just nitpicking, but this:
#include <vector>
#include "Eggs.h"
#ifndef TRAY_H
#define TRAY_H
should be this:
#ifndef TRAY_H
#define TRAY_H
#include <vector>
#include "Eggs.h"
