为什么在标题中的类声明中声明变量时出现错误？ [英] Why am I getting an error when declaring a variable in a class declaration within a header?

问题描述

我想让一个类中有一个简单的整数。当然，它使用头文件和什么。

I'm trying to make a class that has a simple integer with in it. Of course, it uses header files and whatnot.

这里是代码：

class.h

 class consolBuf
{
private:
    int buffersize1 = 10; //Data member initializer is not allowed
    int buffersize2 = 10;
    static char screenBuffer[10][10]; //screenBuffer
public:
    consolBuf(void);
    ~consolBuf(void);
    void draw();
    void write(int x, int y);
    char get(int x, int y);
};

由于某种原因某些共振Visual Studio不断抱怨我不能在类中声明一个整数。 H。我到处搜索，我找不到答案。是否有我遗漏的东西？

For some reason some reson Visual Studio keeps complaining that I can't declare a integer in the class.h. I've searched everywhere and I can't find an answer. Is there something I'm missing?

推荐答案

确实，你不能初始化成员。如果你想初始化那些为每个实例的默认值，你可以在构造函数中这样做：

Indeed you can't initialize members like that. If you wanted to initialize those as default values for each instance, you would do that in the constructor:

consolBuf::consolBuf()
    : buffersize1(10)
    , buffersize2(10)
{

}
