As the saying goes, “a good memory is better than a bad pen”. Adhering to the attitude of convenient review in the later stage, I sorted out a list of basic knowledge points of C++ and presented it in the way of mind map, which is convenient for me to check and fill in the gaps with old friends. In the learning process, the biggest feeling is that C++ really has a higher threshold for entry. Although I have summarized the basic knowledge in C++ Primer fifth edition, I still need some actual practice to polish, so as to reach the standard of entering the industry.
