C++标头保护无法编译

C++ header guards won't compile

本文关键字：编译 保护 C++      更新时间：2023-10-16

不能得到任何代码使用头保护编译在vs 2010。例如:

#ifndef SIMPLE.H
#define SIMPLE.H
#include <iostream>
class Place {
private:
int m_xplace;
int m_yplace;
Place(){}
public:
Place(int x, int y) : m_xplace(x), m_yplace(y) {}
void Move(int x, int y);
void set_place(int x, int y) {m_xplace = x, m_yplace = y;}
int get_place_x() {return m_xplace;}
int get_place_y() {return m_yplace;}
};
#endif

我从编译器得到这样的输出:

1>------ Build started: Project: 1, Configuration: Release Win32 ------
1>e:projects11simple.h(1): warning C4067: unexpected tokens following preprocessor     directive - expected a newline
1>e:projects11simple.h(2): error C2008: '.' : unexpected in macro definition
1>e:projects11simple.h(1): warning C4067: unexpected tokens following preprocessor directive - expected a newline
1>e:projects11simple.h(2): error C2008: '.' : unexpected in macro definition
========== 
Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

我错过了什么明显的东西吗?我很确定我的语法是正确的。谢谢。

不能在标识符中使用.

试试这个:

#ifndef SIMPLE_H
#define SIMPLE_H
