What are the advantages of converting C to golang?

C to golang: Why are more and more developers choosing to use golang for development?

As a powerful programming language, golang is highly respected in various fields, especially in fields such as cloud computing, distributed systems, and web applications. At the same time, C language, the former king, is still widely used in many system-level development and embedded development. With the development of IT technology, more and more developers are turning C to golang. So, what exactly prompted them to do this?

This article will introduce the advantages of converting C to golang from the following three aspects:

1. Advantages of the language itself

2. Improvement of programming efficiency

3. Broadening of application scenarios

1. Advantages of the language itself

Golang is a programming language developed by Google with features such as memory safety, garbage collection, and high concurrency. Compared with C language, golang has many improvements in syntax, type checking, iteration, etc.:

1) Simple syntax

Simple syntax allows developers to write and read code more easily Easily, for example, the defer keyword that comes with golang can make the code more elegant:

defer file.Close()

2) Type mandatory check

Type check can greatly Reduce type conversion and runtime errors and ensure program reliability and robustness. For example, the C language can well extend the robustness of the program on issues such as array out-of-bounds and null pointers, but this robustness is almost done in a static language in golang, and it can even be typed at compile time. Check to avoid these problems.

3) Concurrent programming

Golang can easily implement coroutines, and concurrent execution can be simply achieved in function calls through the go keyword. As shown below:

func printNums(str string) {

for i := 0; i < 5; i++ {
    time.Sleep(100 * time.Millisecond)
    fmt.Printf("%s output %d\n", str, i)
}

}

func main() {

go printNums("goroutine1")
go printNums("goroutine2")
time.Sleep(1000 * time.Millisecond)
fmt.Println("Main finish")

}

2. Improvement of programming efficiency

Simple syntax and built-in libraries can greatly improve programming efficiency and development efficiency. When developers need to perform complex asynchronous calls and network operations, golang's built-in libraries can easily handle it, while C often requires the use of additional libraries.

What’s more noteworthy is that golang can easily manage components through the package management system, which means developers can manage code more easily and reuse code more simply. In addition, golang's compilation speed is also very fast, which means that developers can see the running effect of their code in a short time.

3. Broadening of application scenarios

Golang can be used in fields such as web development, distributed systems, and container ecosystems, while C language is usually used in fields such as operating systems and network protocol stacks. . Golang makes it easy to develop web services and RESTful APIs as it has built-in HTTP router and JSON serializer. In addition, Golang also makes it easy to develop distributed systems such as microservices and container clusters. Because Golang itself has high concurrency characteristics, it can better handle communication and data synchronization between multiple servers.

In short, the process of converting C to golang is a process worth exploring. It allows developers to use more efficient, robust and safer programming methods to build programs, while also expanding application scenarios. While every language has its niche, golang has become a programming language worth paying attention to, constantly evolving and developing, and gradually expanding its influence and application scope.
