矢量对象初始化

Question

I've been wandering on the internet trying to solve some problem in my program. I can't find suffisent information on the Vector object in the documentation about the standards.

So, my question is : what is the default value affected to a newly created Vector object using the default constructor ?

Answer 1

如果您的意思是std::vector ，则默认构造函数将构造一个包含0个元素的空向量。
