go is close to the c language. Go is a C-like high-level language, described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.

Go language is a C-like high-level language

Go language (or Golang) originated in 2007 and was officially released in 2009. Go is a very young language, and its main goal is to "have both the development speed of dynamic languages ​​such as Python and the performance and security of compiled languages ​​such as C/C."

Go language is a computer programming language similar to C language, C language, Python, and Java.

The Go language is sometimes described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.

Go language is another attempt at programming language design and a major improvement over C-like languages. It not only allows you to access the underlying operating system, but also provides powerful network programming and concurrent programming support. Go language has many uses and can be used for network programming, system programming, concurrent programming, and distributed programming.

The difference between Go language and C language

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.

Source file comparison

  • C language source file
File extension Source type
.h Header file, storing code declaration
.c C language source file, storing code implementation
  • Go language source file
File extension Source type
.go Go language source file, storing code Implementation

Comparison of code management

  • Manage code through files in C language
    • Want to use For a certain function, you only need to include the corresponding .h file.
  • Go language uses packages to manage code
    • Go language does not have the concept of .h file , when you want to use a certain function in Go, you only need to import the corresponding package
  • Public and private management of functions and variables in C language
    • Through extern and Static implements whether to expose functions and variables
  • Public and private management of functions and variables in Go language
    • Implements whether to expose functions by capitalizing the first letter of the function name
    • Realize whether to expose variables by case of the first letter of the variable name

Comparison of keywords

  • There are total in C language 32 keywords
##1234 5678##elseswitchcasedefaultwhilestructcharshortintlongfloatdoublevoidsizeofsignedunsignedconststaticexternvolatile
  • There are a total of 25 keywords in Go language

    Essence
    Like C language, Go language also supports single-line comments and multi-line comments, and all comments The features are the same as those of C language

    Single-line comments//Commented content

      Multi-line comments
    • /*Commented content*/
      • In the Go language, it is officially recommended to use single-line comments instead of multi-line comments (for details, you can directly view the Go official source code)
