The difference between golang and c

Golang and C each have their own advantages and disadvantages, as well as different application scenarios. There are major differences in performance, syntax, concurrency, readability, ecology, etc.

1. Syntax differences

Programming language syntax is the first step for programmers to get started. C’s syntax focuses on programmers’ control of details, but the code complexity is high and it is difficult to write Efficient and correct code. The Golang language uses simpler syntax to simplify the programming process and supports OOP programming, shortening development and debugging time.

C has pointers and can directly operate on memory. But this also brings risks to the program, and if used improperly, it can cause the program to crash. Golang's pointers are usually used less to simplify programming for programmers.

2. Performance Difference

C language is known for its high efficiency and is particularly suitable for writing high-performance, system-level code. The C language compiler and runtime are implemented in C language, so they have higher execution efficiency. The running efficiency and memory usage efficiency of C language code are higher than that of Golang.

Golang is a new programming language open sourced by Google. When it was designed, it focused on high concurrency and efficiency. Golang makes the program run faster by supporting concurrency, and is especially suitable for scenarios that deal with large amounts of data and high concurrency. But compared to C language, Golang's running efficiency is slightly inferior.

3. Concurrency Differences

Golang has obvious advantages in dealing with high concurrency and distributed computing. Golang provides mechanisms such as locks and pipes to make concurrent and coroutine programming more convenient. Golang supports many developers for thread and coroutine programming, and uses the goroutine and channel mechanisms to complete data processing and message passing, making the code written by programmers easier to debug, optimize and expand.

The C language does not directly support coroutines and concurrent programming, nor is it as simple to implement as in the Go language. Although the C language can also implement multi-threading and coroutine programming through libraries such as pthread, programmers need to maintain locks and synchronization schemes themselves and write complex and error-prone code.

4. Readability

In terms of readability, Golang is more friendly than C language. Golang adopts simple syntax and language structure, and the code is standardized, easy to understand and maintain. In contrast, the code structure and syntax of C language are more complex, tend to feel verbose, and are also more difficult to read. In the development of large-scale software, the requirements for code readability and maintainability are high, and Golang is better than C language.

5. Ecological Support

C language has been widely used in various computer fields and has mature technology and a large number of developers. The C language development ecosystem is very large and supports the development of a variety of software including operating systems, compilers, libraries, etc.

Golang is relatively young, but it already has a quite rich ecosystem. Golang supports web applications, back-end development, system programming and other application development, and has many open source frameworks and libraries, providing developers with more choices.

Conclusion:

To sum up, both Golang and C language have their own advantages and disadvantages and are suitable for different application scenarios. There are differences in performance, readability, syntax, concurrency, and ecology. C language is suitable for writing system-level code, while Golang is suitable for high-concurrency and distributed system development. If it is a large-scale software development with complex links and difficult maintenance, Golang is better than C language.
