Which part of a Golang function comment is used to describe the parameters of a function?

In Go function comments, the part used to describe the function parameters starts with the @param symbol, followed by the parameter name and description. The syntax is: @param name description (for example: @param length: the length of the side of the cube)

Parameter description in Go function comments

In Golang, function comments are documentation strings used to describe function behavior and purpose. The comment contains several sections, one of which is dedicated to describing the parameters of the function.

Parameter description part

The parameter description part usually starts with the @param symbol, followed by the parameter name and description. Its syntax is as follows:

@param name description

For example:

// AddTwoNumbers returns the sum of two integers.
func AddTwoNumbers(a int, b int) int {
    // Add the two integers.
    return a + b
}

In this example, the part after the @param symbol describes the two parts of the AddTwoNumbers function Parameters: a and b.

Practical case

Let us write a function to calculate the volume of a cube and add comments to its parameters:

// VolumeOfCube calculates the volume of a cube with specified length.
func VolumeOfCube(length float64) float64 {
    // Calculate the volume of the cube.
    return length * length * length
}

Instructions:

• @param length: Describes the length parameter of the function. This is the side length of the cube whose volume is to be calculated.
• Comments can also contain additional information, such as default values ​​or limits for parameters.

Tip:

• Make sure the comments are accurate and useful.
• Use clear and simple language.
• Follow the established style guide within your team or organization.
