类的静态常量初始化

class A

{

private:

      static const int a = 0;  //正确

      static const char b = 'b';  //正确

      const int c = 0; //错误，非static const不能在类里面初始化

      static const int d[10] = {0}; //错误，只有一般数据类型的static const才能在类里面初始化。

                                                   //数组应该在.cpp文件里面初始化

}

 

 

数组初始化问题：

int a[5] = {0};  //相当于 int a[5] = {0,0,0,0,0};

int a[5] = {1};  //相当于 int a[5] = {1,0,0,0,0};

int a[5] = {1,2,3,4,5};

int a[] = {1,2,3,4,5};
