是否可以避免在实现文件中重复类名？ [英] Is it possible to avoid repeating the class name in the implementation file?

问题描述

有没有办法避免在实现文件中的 Graph :: 重复，但仍然将类拆分成header +实现？例如：

标头档案：

  #ifndef Graph_H 
 #define Graph_H 
 
类图{
 public：
 Graph（int n）; 
 void printGraph（）; 
 void addEdge（）; 
 void removeEdge（）; 
}; 
 
 #endif 
  

实施文件：

  Graph :: Graph（int n）{} 
 void Graph :: printGraph（）{} 
 void Graph :: addEdge {} 
 void Graph :: removeEdge（）{} 
  

解决方案>

我猜这是为了避免大量的不必要的打字。可悲的是，没有办法摆脱范围（因为许多其他答案已告诉你）但是我个人的做法是将所有我的函数原型定义在漂亮的行，然后复制/粘贴到实现文件然后ctrl-c您的ClassName ::在剪贴板和运行与ctrl-v。

行

Is there a way to avoid the Graph:: repetition in the implementation file, yet still split the class into header + implementation? Such as in:

Header File:

#ifndef Graph_H
#define Graph_H

class Graph {
public:
    Graph(int n);
    void printGraph();
    void addEdge();
    void removeEdge();
};

#endif

Implementation File:

Graph::Graph(int n){}
void Graph::printGraph(){}
void Graph::addEdge(){}
void Graph::removeEdge(){}

解决方案

I'm guessing this is to avoid lots of "unnecessary typing". Sadly there's no way to get rid of the scope (as many other answers have told you) however what I do personally is get the class defined with all my function prototypes in nice rows, then copy/paste into the implementation file then ctrl-c your ClassName:: on the clip board and run up the line with ctrl-v.
