Summary of the advantages and disadvantages of C++ and Python programming languages, and share my views on programmer career planning

Today I mainly want to talk about some personal thoughts on programmer career planning. If you're already a programmer, consider this some of my ideas, and drop me a line if you have other ideas. If you have not yet entered the industry of programmers or are considering changing careers, then you can regard this as an introduction to the basic knowledge background of a programmer.

Mainly discuss from four aspects. The first point is the differentiation of programmer ranks, the second point is the introduction of internal ranks, the third point is the direction selection of the front and back ends, and the fourth point is about the handling of the 35-year-old career crisis.

At present, the direct division of ranks widely recognized on the market is mainly primary, intermediate and senior. The junior level is generally prepared for graduates who have just graduated for 1-3 years, and they may need to ask others for help in their tasks. After the intermediate level has gone through multiple tasks, their proficiency in software development has improved. Their relationship with the junior level is equivalent to that of small workers and skilled workers, which can be understood in this way. At this stage, they can already complete the tasks assigned by their superiors efficiently and with high quality.

At an advanced stage, they can be considered architects. At this stage, you need to have a fairly deep understanding of software. After years of deep cultivation in the software industry, you have a relatively comprehensive understanding of software development and a big picture.

Inside Dachang, the primary level is divided into two levels, 59 and 60. Junior personnel, whether they are undergraduate or graduate students, may be assigned to level 59. After another year or two or half a year, depending on different projects and personal abilities, you may be promoted to level 60, and generally stay in the primary stage for 2-3 years.

The intermediate level is subdivided into 61 and 62 levels, and may stay at this stage for 5-6 years. Of course, these are not guaranteed, because personal abilities and projects will affect the rank, including whether the department is in a stage of rapid development. Boost speed. But basically this time. Some people recruited by the agency may be given a relatively low rank because their salary is linked to their rank, but this does not mean that this person is not capable, and these are relatively special circumstances.

At the advanced stage, careers begin to diverge, divided into two directions: technology and management. You can choose to lead a small team for management, or you can choose to lead a project for advanced software development. But no matter how high the level is, it may be a radish and a pit. Unless there is a relatively large turmoil or a new department needs to be established, the ceiling for ordinary people’s technical personnel is advanced development, and it may stay for many, many years. These are normal. matter.

The advantages and disadvantages of C++ and Python can be summarized as follows:

Advantages of C++

• Efficiency: C++ is a system-level language that can directly operate the underlying hardware and operating system. It has efficient runtime performance and flexible compile-time features. It can further improve program performance through compiler optimization and memory pool technologies. .
• Controllability: C++ can finely control the use of memory and resources to avoid problems such as memory leaks and memory overflows. At the same time, RAII and other technologies can be used to realize automatic management of resources and improve program reliability and maintainability.
• Strong type: C++ is a strongly typed language, which can catch most type errors at compile time and improve the robustness and maintainability of the code.
• Multithreading: C++ multithreading programming can help programmers make better use of multi-core CPUs and improve the concurrency and responsiveness of programs.

Disadvantages of C++

• Steep learning curve: C++ is a relatively complex language, and there are many knowledge points to be mastered, so the learning curve is relatively steep.
• Security: C++ requires the programmer to be responsible for the management of memory and resources, which is prone to problems such as memory leaks and out-of-bounds access. Programmers need to have certain security awareness and experience.
• Low development efficiency: The syntax of C++ is relatively cumbersome, requiring programmers to write more codes, and the development efficiency is relatively low.

Advantages of Python

• Concise and easy to learn: The syntax of Python is relatively concise, easy to learn and master, and can quickly realize various functions.
• Efficient development: Python has a relatively high development efficiency, and can quickly build various applications through various libraries and frameworks.
• Excellent ecosystem: Python has a wide range of application scenarios, rich libraries and frameworks, and can quickly build various applications.
• Strong readability: Python code is relatively easy to read and understand, which can improve the maintainability and readability of the code.

Disadvantages of Python

• Poor runtime performance: Python is an interpreted language with poor runtime performance, which needs to be improved through technologies such as JIT.
• Weak type: Python is a weakly typed language. Type errors need to be caught at runtime, which is prone to errors.
• Poor controllability: Python has relatively loose management of memory and resources, which is prone to problems such as memory leaks, requiring programmers to have certain security awareness and experience.
• Not suitable for low-level development: Python is not suitable for low-level development, such as operating systems, drivers and other fields.

The knowledge points that C++ programmers need to understand in depth include but are not limited to the following aspects:

• Object-oriented features: C++, as an object-oriented language, has features such as classes, inheritance, and polymorphism, making it easier for programmers to design and maintain code.
• Standard Template Library (STL): C++'s STL includes various containers, iterators, and algorithms, which can help programmers simplify code and improve code readability and maintainability.
• Memory management: C++ can achieve fine management of memory through technologies such as dynamic allocation of memory and smart pointers, and avoid problems such as memory leaks and memory overflows.
• Multi-thread programming: C++ multi-thread programming can help programmers make better use of multi-core CPUs and improve the concurrency and responsiveness of programs.
• Performance optimization: C++ has high-efficiency runtime performance and flexible compile-time features, and can further improve program performance through compiler optimization and memory pool technologies.

Compared with other programming languages, the advantage of C++ is that it is a system-level language that can directly operate the underlying hardware and operating system, allowing programmers to better control the operating environment of the code. At the same time, C++ has a wide range of application scenarios and plays an important role in fields such as games, finance, and scientific computing.

In short, as a C++ programmer, on the basis of mastering the above knowledge points, you need to continue to learn and explore, improve your programming ability and practical experience, in order to cope with the increasingly complex software development work.
