I usually only use Python, do not pursue speed when doing some simple mathematical calculation is very convenient, but the work must learn C + +.
Reply content:
I also learned the C + + of Python before learning. Learning Python has some advantages in understanding Oo, but it also makes you spoiled to think C + + is troublesome, and many tools are not intuitive. Here is my step-by-step route:
Basics: Find an introductory open class, such as introduction to C + + on MIT OCW
, or our school's CS11 C + + track
, slides the last few exercises and write a quick overview of the basic syntax of C + +.
Advanced: In Oj.leetcode and more advanced online judge on the more difficult topic (through rate <20%) in C + + to write again, to practice using some of the STL basic classes such as unordered_map, vectors, maps and so on. You can then look at some more advanced courses, such as MIT's effective programming in C and C + +
Or our school's CS11 advanced C + + track
。 Learn and practise concepts such as template and class inheritance.
Advanced: Reading. Effective C + + and C + + primer have to be seen at this level, and learn new things in c++11. In addition, summer internship when the group has a GETCO job-hopping to the C + + God sitting next to me, recommended a very good class called performance Engineering of software Systems
。 He says this class is basically for the Quant Trading system, very practical.
Of course, my "basic/Advanced" Here is for my slag level, you laughed at the great God. But since the title and I are peers, presumably to learn C + + is to develop trading strategies, then I think the above three steps to complete the basic enough. Is CPP difficult? When the use of the time to look at it, the meaning of voidness is not very accelerated C + + (watercress)
C++primer + effective C + + What do I think from Python to C + + and your algorithmic math doesn't matter. Writing a good program is a better algorithm, but learning how to use the language seems to have nothing to do with the algorithm. Python Dafa good, back CPP to protect the peace! Not proficient in C to learn C + +, there will be trouble, this thing is not fast. If you can use C to implement a variety of complex algorithms, and then to learn C + +, it will be much easier I think someone will let you go through his posts the differences between Python and C + + are mainly in two big ways: Python is a dynamic language, and C + + is a static language (but C11 also introduces a dynamic concept in C + +). such as lambda and auto, etc.), this is the one hand, and the code is not the same format, Python is indented by the way to define the scope, and C + + is through braces and so on. All the others are connected. I've tried python, but I can't stand the way he's indented! Personal C + + is much more time than python to casually say ...
