I have a question about stacks... I want to write a program with 3stacks and I want to add this operations on each of these stacks( I should use arrays):
我有一个关于堆栈的问题...我想编写一个带有3stacks的程序，我想在每个堆栈上添加这些操作（我应该使用数组）：
1.create the stack 2. push number 3.pop number 4. display the top of each stack
1.创建堆栈2.按数字3.pop数字4.显示每个堆栈的顶部
I wrote the program but I encountered these errors:
我写了程序，但我遇到了这些错误：
Error 4 error LNK2019: unresolved external symbol "public: int __thiscall stack::IsFull2(void)" (?IsFull2@stack@@QAEHXZ) referenced in function "public: void __thiscall stack::Push2(void)" (?Push2@stack@@QAEXXZ) C:\Users\Princess\Documents\Visual Studio 2012\Projects\Project9\Project9\Source.obj

错误5错误LNK1120：1个未解析的外部C：\ Users \ Princess \ Documents \ Visual Studio 2012 \ Projects \ Project9 \ Debug \ Project9.exe 1
what should I do in order to solve these errors?

Exactly what the error says: you did not define the IsFull2 method in your code, but you use it inside the stack::Push2 method. You need to write the body of stack::IsFull2 or change your code so it does not call it (an then remove the declaration too).
确切地说错误是什么：你没有在你的代码中定义IsFull2方法，但你在stack :: Push2方法中使用它。您需要编写stack :: IsFull2的主体或更改您的代码，以便它不会调用它（然后删除声明）。
