Your Decode function as an example has a reference to a class type as the function declaration in the class definition. But you start off the function definition with a pointer to a basic type.In order to match function declarations to the function body, the compiler will match the ...
C.82: Don't call virtual functions in constructors and destructors C.82:不要在构造函数或析构函数中调用虚函数 Reason(原因) The function called will be that of the object constructed so far, rather than a possibly overriding function in a derived class. This can be most confusing. Worse, ...
GNU C 的一大特色就是__attribute__ 机制。__attribute__ 可以设置函数属性(Function Attribute )、变量属性(Variable Attribute )和类型属性(Type Attribute )。 __attribute__ 书写特征是:__attribute__ 前后都有两个下划线,并切后面会紧跟一对原括弧,括弧里面是相应的__attribute__ 参数。
慢慢说来,不要以为gcc只能编译C代码,g++只能编译c++代码。 后缀为.c的,gcc把它当作是C程序,而g++当作是c++程序;后缀为.cpp的,两者都会认为是c++程序,注意,虽然c++是c的超集,但是两者对语法的要求是有区别的。在编译阶段,g++会调用gcc,对于c++代码,两者是等价的,但是因为gcc命令不能自动和C++程序使用的库联接,...
