从C ++中的同一类的另一个成员函数中调用成员函数，目标C.
问题描述：
请考虑以下内容：
class A{
//data members
void foo()
{
bar();//is this possible? or should you say this->bar() note that bar is not static
}
void bar()
{
}
}//end of class A
如何从另一个函数中调用成员函数？静态函数如何影响'this'的使用。
应该在对象上调用函数？
How do you call member functions from within another? And how does static functions affect the use of 'this'. Should functions be called on an object?
答
Nawaz是正确的：'this'一个例外是如果foo是一个静态函数，因为在静态函数中没有this。在这种情况下，你不能使用bar（），除非bar（）也是一个静态函数，你不能使用this-> bar（）。
Nawaz is correct: 'this' is implicit. The one exception is if foo were a static function, because in static functions there is no 'this'. In that case, you can't use bar() unless bar() is also a static function, and you can't use this->bar() at all.
