What is the difference between golang and C language?

The difference between golang and C language: 1. Golang is an object-oriented programming language, while C language is a process-oriented programming language; 2. Golang manages code through packages, while C language uses files to manage code; 3. There are 25 keywords in golang, while there are 32 keywords in C language; 4. The memory occupied is different; 5. The formats for defining constants and variables are different; 6. Golang introduces garbage collection The mechanism will automatically manage memory, while C language requires manual management of memory and so on.

The operating environment of this tutorial: Windows 10 system, GO version 1.20, Dell G3 computer.

Go (also known as Golang) is a statically strongly typed, compiled, concurrent programming language with garbage collection capabilities developed by Google.

Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages ​​that adopt a similar model include Occam and Limbo, but it also has features of Pi operations, such as channel transmission. Plugin support is opened in version 1.8, which means that some functions can now be dynamically loaded from Go.

C language is a process-oriented, abstract, general-purpose programming language that is widely used in low-level development. C language can compile and process low-level memory in a simple way. C language is an efficient programming language that only generates a small amount of machine language and can run without any operating environment support. Although the C language provides many low-level processing functions, it still maintains cross-platform characteristics. C language programs written in a standard specification can be executed on many computer platforms including operating platforms such as embedded processors and supercomputers. Compile.

The difference between go and c language

1. C language is a process-oriented programming language, while golang is an object-oriented programming language ;

2. In C language, code is managed through files, while in Go language, code is managed through packages.

3. There are a total of 32 keywords in C language, a total of 25 keywords in Go language, etc.

4. Different memory occupations

Each data type in C language occupies memory space

Go Each data type of the language occupies memory space

5. Comparison of constant variables

C language definition of constant and variable format

数据类型 变量名称 = 值;<br/>const 数据类型 常量名称 = 值;<br/>

Go language defines constant and variable formats

In addition to the following standard formats, Go language also provides several simple syntactic sugars

var 变量名称 数据类型 = 值;<br/>const 变量名称 数据类型 = 值;<br/>

6. Memory management

C language requires programmers to manually manage memory, including allocation and release. If programmers do not manage memory properly, problems such as memory leaks or dangling pointers may easily occur. The Go language introduces a garbage collection mechanism to automatically manage memory and avoid many such problems. Programmers do not need to worry about memory allocation and release issues and can better focus on writing business code. At the same time, the Go language has also optimized memory allocation. Through mechanisms such as caching, memory can be allocated and recycled faster, improving program performance.

7. Concurrent programming

Go language is naturally suitable for concurrent programming. It has built-in goroutine and channel, which can transfer data between different goroutines. These features allow programmers to easily write concurrent programs while ensuring program stability. Of course, C language can also perform concurrent programming, but it requires manual management of threads and locks, which is too cumbersome and complicated.

8. Syntax type

C language is a statically typed language, and the type of variables needs to be determined at compile time. The Go language is a dynamically typed language that can dynamically determine the type of variables at runtime. This makes the Go language more flexible, but it is also prone to type errors and requires developers to write code very carefully.

10. Coding style

The coding style of C language is relatively unique. Braces are generally used to enclose code blocks, and then line breaks are indented. The Go language pays more attention to the simplicity and readability of the code. Code blocks are represented by indentation, and there are also some syntactic sugars to simplify code writing. At the same time, the Go language also has its own naming convention, which can reduce naming conflicts among programmers.

In short, although C language is more traditional than Go language in many aspects, some features of Go language are indeed very suitable for modern software development. By comparing Golang with C, we believe readers have been able to better understand the differences between them. No matter which language we choose, we should choose it based on specific needs, rather than blindly pursuing the trend of a language.
