Understand the origin of Golang and C language

Go language (also known as Golang) and C language, as two popular programming languages, are closely related in many aspects. This article will take you to understand the origins of Golang and C language, and show the similarities and differences between them through specific code examples.

Part One: The Origin of Golang and C Language
Go language is a static programming language developed by Google and was first publicly released in 2009. The design goal of Go language is to improve programming efficiency, simplify code structure, and improve concurrency performance, while retaining the performance and efficiency of C language. Therefore, we can see that Golang is influenced and borrowed from the C language in many aspects.

C language is a classic programming language invented in 1972 by Dennis Ritchie of Bell Labs. C language is famous for its simplicity, efficiency, and flexibility, and has become the basis of many programming languages, such as C, Java, Python, etc. Golang clearly expressed its admiration and reference for the C language from the beginning of its design, which also makes Golang and the C language similar in many aspects.

Part 2: Code Example

1. Variable declaration and assignment
   Variable declaration and assignment in C language:

   int a = 10;

Variable declaration and assignment in Go language:

a := 10

In terms of variable declaration and assignment, Golang adopts a more concise syntax and uses the ":=" operator to declare and assign variables.

2. Function definition and calling
   Function definition and calling in C language:

   #include <stdio.h>
   
   void printHello() {
    printf("Hello, World!
   ");
   }
   
   int main() {
    printHello();
    return 0;
   }

Function definition and calling in Go language:

package main

import "fmt"

func printHello() {
    fmt.Println("Hello, World!")
}

func main() {
    printHello()
}

In terms of function definition and calling, the writing methods of Golang and C language are relatively similar. They both use the keyword "func" to define the function and use the function name to call the function.

3. Definition and traversal of arrays
   Array definition and traversal in C language:

   #include <stdio.h>
   
   int main() {
    int arr[5] = {1, 2, 3, 4, 5};
    
    for(int i = 0; i < 5; i++) {
        printf("%d ", arr[i]);
    }
    
    return 0;
   }

Array definition and traversal in Go language:

package main

import "fmt"

func main() {
    arr := [5]int{1, 2, 3, 4, 5}
    
    for i := 0; i < len(arr); i++ {
        fmt.Print(arr[i], " ")
    }
}

In terms of the definition and traversal of arrays, Golang has certain similarities with the syntax of C language. They both use "[]" to define arrays and use indexes to traverse array elements.

Part 3: Summary
Through the comparison of the above code examples, we can see that Golang and C language have certain similarities in grammatical structure and expression. This also makes it easier for programmers with a C language foundation to learn and master Golang. At the same time, Golang has also been improved and improved in many aspects, making the code more concise and efficient. The origin of Golang and C language is not only reflected in the similarity in syntax, but also in the pursuit of programming efficiency and performance optimization.

I hope that through the introduction of this article, you can have a deeper understanding of the origins of Golang and C language, and experience the connections and differences between them through specific code examples, so as to better master these two programmings. language. I hope this article can help you better understand Golang and C language, and provide some help and inspiration for your programming journey.
