保持理智的c ++标头
|
我似乎在用c ++进行编码时遇到的最大问题是，必须先声明一个类，然后才能引用它。说我有两个这样的头文件...
头文件1.h
#include \"Header2.h\"
#include <deque>
#include <string>
#include <iostream>
using namespace std;
class HelloPackage;
class Hello
{
public:
string Message;
HelloPackage * Package;
Hello():Message(\"\")
{
}
Hello(string message, HelloPackage * pack)
{
Message = message;
Package = pack;
}
void Execute()
{
cout << Message << endl;
//HelloPackage->NothingReally doesn\'t exist.
//this is the issue essentially
Package->NothingReally(8);
}
};
#include \"Header1.h\"
#include <deque>
#include <string>
#include <iostream>
using namespace std;
class HelloPackage
{
public:
deque<Hello> Hellos;
HelloPackage()
{
Hellos = deque<Hello>();
}
int AddHello(string Message)
{
Hellos.push_back(Hello(Message,this));
}
void ExecuteAll()
{
for each(Hello h in Hellos)
h.Execute();
}
int NothingReally(int y)
{
int a = 0;
a += 1;
return a + y;
}
}
