As two programming languages, Golang and C are similar and different in many aspects. Next, let’s discuss the differences between Golang and C.

Language Origin

C language - was born in the 1970s. The syntax was originally written by Dennis Ritchie. At that time, it was mainly used in programming Unix systems. The Golang language was born (also called Golang) as a programming language developed by Google in 2007. Golang is a high-performance, scalable and modern programming language developed by Google and has been praised by many people.

Type system

Golang has a more strict type system and treats the same type as having similar behavior and properties. Golang provides an interface-based type system, which provides developers with a lot of convenience and also makes it easy to implement interface reuse.

In contrast, the type system of C language is relatively simple and can be regarded as a weakly typed language. In C language, there is no explicit definition of enumeration variables, and there is no separate representation of string types.

Memory Management

C language uses a manual memory management method, which requires programmers to handle memory management by themselves. Programmers must allocate and free memory carefully, otherwise the program may crash due to memory allocation and freeing errors. Golang provides an automatic memory management mechanism based on garbage collection. When declaring variables and creating slices, memory is automatically allocated and released.

Concurrency support

C language is not very friendly to concurrent programming, but Go has high concurrent programming capabilities. Golang provides its own goroutine, channel and other concurrent operation mechanisms, which can better improve program efficiency in big data scenarios.

Code Reuse

The Go language has its own package management mechanism, which is modular management. Correspondingly, the C language fails to provide a similar mechanism, and code often needs to be reused by sharing header files and source files.

Compilation speed

Golang language is definitely better than C language in terms of compilation speed. Under normal circumstances, Golang programs can be compiled within a few seconds.

In general, Golang is more modern, easier to use and simpler than C language. There are many differences between the two languages in terms of application scenarios, programming methods, and writing code. Although the development purposes of the two programming languages are different, the choice of which programming language to use still depends on the specific application scenario.

Learn Go String Manipulation: Working with the 'strings' PackageMay 09, 2025 am 12:07 AM

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go: String Manipulation with the Standard 'strings' PackageMay 09, 2025 am 12:07 AM

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go bytes package: short reference and tipsMay 08, 2025 am 12:05 AM

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.
