Is golang a compiled language?

golang is a compiled language. Programming languages ​​can be divided into compiled languages ​​and interpreted languages. Compiled languages ​​convert source code into machine language at compile time and then execute the generated machine code. Interpreted languages ​​interpret the source code line by line at runtime and execute it accordingly. program. Golang's compilation process is divided into four main stages: lexical analysis, syntax analysis, semantic analysis and code generation.

So, is Golang a compiled language?

Yes, Golang is a compiled language. It was developed by Google and first released in 2009. Golang's design goal is to provide a fast, safe, simple and efficient programming language. It uses static typing, garbage collection, and concurrent programming models to support high-concurrency, high-performance application development.

Compared with some traditional compiled languages, Golang has some unique characteristics. First of all, Golang's compiler is very fast and can convert the code from source code to executable file in seconds. Secondly, Golang's compiler is based on LLVM, which enables it to generate highly optimized machine code. In addition, Golang also supports cross-compilation, that is, it can be compiled on one machine into executable files under other operating systems and platforms.

Golang’s compilation process is divided into four main stages: lexical analysis, syntax analysis, semantic analysis and code generation. First, the compiler performs lexical analysis on the source code and divides it into a series of tokens. The compiler then performs syntax analysis to determine whether the structure and syntax of the source code are correct. Next, the compiler performs semantic analysis, checks whether the declaration and use of variables comply with the language specifications, and performs type checking. Finally, the compiler generates machine code based on the results of semantic analysis and saves it as an executable file.

At runtime, Golang's compiler no longer needs to be involved because it has already converted the source code into an executable file. At this point, the user only needs to run the generated executable file. This makes Golang's execution speed very fast and does not require an additional runtime environment (such as a Java virtual machine).

In general, Golang is a compiled language. It features fast compilation and execution speeds, highly optimized machine code generation, and support for cross-compilation. These features make Golang ideal for developing high-performance, concurrent applications.

Writing style

There are several regulations in Go. When the following regulations are not matched, compilation will produce an error.

1. There is no need to write a semicolon (;) after each line of the program.

2. Braces ({) cannot be placed in new lines.

3. If judgments and for loops do not need to be enclosed in parentheses.

Go also has a built-in gofmt tool, which can automatically sort out excess whitespace in the code, align variable names, and convert aligned spaces into tabs.
