My colleague gave me a few questions. 1. Introduce STL and explain in detail how STL implements vector. 4. What are the differences between pointer and reference? If it is safer to pass a reference than to pass a pointer, why? Isn't it true if I use

There is nothing to worry about. Considering a previous problem, it is necessary to use STD: vector to store data. If the stored data volume is large or there is not enough memory, what should I do, considering the concept of virtual memory when

Gunshuo's written test mainly involves Java and C ++ in terms of language. It adds a C # question and writes it down when I remember it.   1. A binary tree is provided with a forward and central traversal, which requires a post-order

With the development of computer language, it is more and more easy to compile a program. With some software development tools, the computer will automatically generate a lot of code by dragging the mouse. However, in many cases, this kind of
