c++ - 非技术问题：刚入职的应届毕业生程序猿领导要求要马上入手项目，如何快速入手？

Question

给的文档说的不详细，注释几乎没有，虽然领导给我讲的我需要写的需求懂了，可是代码完全不懂，一行一行看代码的话，短时间内根本看不完，可见这不是一个好办法。
主要问题是，对项目源码无从下手，或者说想问下如何在最短的时间内去熟悉源码，从而知道该如何下手，该去继承那些类，使用到哪些类？
求各位过来人指点。

Answer 1

How many lines of LOC?
The most important thing about C++ is to compile, run, and debug the code. After debugging and running the latest code, look down the main line. After distinguishing the core business from the peripheral business, you will know that not all the code It’s all about everything

Answer 2

In this case, start debugging and then read on... wherever you use it, don't think about reading it all at once.

Answer 3

There is no solution to your problem. It’s not a bad thing to get some experience and prepare to resign during the probation period.
Generally speaking, it is necessary to read the source code, but there are very few places where you need to read it line by line. Generally, it is enough to see the class name and method, and you can roughly guess what it means. Otherwise, you can only talk about the class and method. There is a problem with the naming.
Besides, it is not a good practice to code without corresponding comments.

Judging from what you said, the so-called leadership or senior level is just that. If you find a good team in another company, you will grow faster.

The recruiter should know that you are a fresh graduate and you definitely have no experience. They need to tell you many things step by step and work with you for at least 3 days. If he does not have this awareness...

Answer 4

It would be better if an experienced driver from the company briefly explains the functions of each module

Answer 5

First compile and run it, then try to use the program yourself to understand its functions. Finally, look at the code according to function.
First know how to use it, then look at the code.
