# Zig Comments
Comments are not processed by the compiler, and are only used to add explanations and notes in the code to help developers understand the code logic.
In Zig, comments come in two forms: single-line comments and multi-line comments.
## 1. Single-line Comments
Single-line comments start with //, and the comment content runs from // to the end of the line.
## Example
const std = @import("std");
// This is a single-line comment
pub fn main()void{
std.debug.print("Hello, World!n", .{});
}
## 2. Multi-line Comments
Multi-line comments start with /* and end with */, and the comment content can span multiple lines.
## Example
const std = @import("std");
/*
This is a multi-line comment
Can span multiple lines
*/
pub fn main()void{
std.debug.print("Hello, World!n", .{});
}
## Using Comments
The following is a complete example containing both single-line and multi-line comments, demonstrating how to add comments in code.
## Example
const std = @import("std");
// Main function
pub fn main()void{
// Call std.debug.print function to print "Hello, World!"
std.debug.print("Hello, World!n", .{});
/*
This code demonstrates Zig's basic syntax
Including function definition, standard library usage, and comments
*/
const a: i32 =10;// Define an integer constant a with value 10
const b: i32 =20;// Define another integer constant b with value 20
// Call add function and print the result
const result = add(a, b);
std.debug.print("Result: {}n", .{result});
}
// A simple addition function
fn add(a: i32, b: i32) i32 {
return a + b;
}
* Single-line comments are used to explain individual lines or local code segments in the code.
* Multi-line comments are used to explain larger sections of code.
