运算符重载问题。

[ra3]

运算符重载具体该怎么做？可不可以举一个简单一些的例子。这个问题太难了。

//...

[prototype]

it is actually the same as you overload the normal functions. only need to pay attention to the requirement for the arguments for each particular operator.

for example. only 1 arugment is allowed for 'operator []'. in your class, you can define it as:

class A{
A& operator [] ( int a ) { ... }
};

[ra3]

class A{
A& operator [] ( int a ) { ... }
};

把它这样定义，可以做什么呢？

[prototype]

a more complete example to show what it can do:

class A{
int i;
public:
A& operator[] ( int a ) { i = a; return *this; }
void f() { cout << i; }
};

A b;

a[1].f(); // output '1'.


i am sure you can think of better use of the operator[].

我明白了，谢谢！

函数重载明白吗？运算符重载其实是一样的道理。你应该这样理解。
