构造函数参数问题C ++ [英] Constructor Parameter issue C++

问题描述

我有一个类的构造函数接受一个bool，指向数组和字符串的指针。

I have a constructor for a class that takes in a bool, a pointer to an array, and string.

TheConstructor(bool theBool=true, int *theArray=0, std::string message="0");

这是否正确的方式写入头文件？我的程序现在不是编译，因为一个未定义的引用构造函数和其他成员函数。

Is this the correct way to write it in the header file? My program isn't compiling right now because of a "undefined reference to "the constructor" and to other member functions".

这可能是什么原因？我检查和在main.cpp我#includedClass.h和定义每一个需要定义的成员函数，在Class.h中写的Class.cpp

What could be causing this also? I checked and in main.cpp I #included "Class.h" and defined every memberwise function that needed to be defined that was stated in "Class.h" I wrote in "Class.cpp"

推荐答案

我希望你没有命名你的类 TheConstructor :)如果你有< c> C 你可以声明它的构造函数几乎与你一样 - 你忘了放置 bool 参数的名称：

I hope you didn't name your class TheConstructor :) If you have class C you can declare its constructor almost as you did - you forgot to put the name of the bool argument:

Ch：

#include <string>

class C
{
public:    
    C(bool b = 0, int *theArray = 0, std::string message = "0");
};

C.cpp：

#include "C.h"
C::C(bool b, int *theArray, std::string message)
{

}
