Learn Golang from ChatGPT
Sound interesting?
Yeah!! Today we will learn how to learn something new with the help of chatGPT. In order to prepare for this, we will learn the Go language today.
Let's ask chatGPT what Golang is.
amazing, huh? Now we know what Golang is.
Let's assume we have no prior knowledge of Golang. So, let's ask for a road map.
It provides us with a general summary, right? as a result, our sequential lifecycle might look like this.
Let's get acquainted with the syntax of Golang now. What will the answer be from ChatGPT?
wow!!! There might be no need for further explanation. So, there could be a few things we have like-
Let's go through them one by one, beginning with variables.
Variable:
Is there any more to say about variables? Isn't the answer a resounding no?
Then proceed to ‘Types’.
Golang also supports user define types like as —
Control Structure?
There are various types of control structures. Let's talk about them now.
If-else statement:
Switch Statement: switch
statements used to select one of several code blocks to execute based on a value.
For Loop:
For loop used to repeatedly execute a block of code. Go has several forms of the for
loop, including:
Now lets take a look in golang function.
Function
A function in Go is a reusable piece of code that takes parameters and returns a value.
Let’s dive into golang pointer.
Pointer:
Pointer holds the memory address of a value.
Syntax:
Example:
The time has come to enter interface and leave function.
Interface:
An interface in Go is a type that defines a set of methods but leaves their implementation to concrete types.
Syntax:
Example:
In this example, an interface Shape
is defined with one method Area
that takes no parameters and returns a float64
. A struct Rectangle
is then defined with width
and height
fields of type float64
. The Rectangle
struct implements the Shape
interface by defining a method named Area
that calculates and returns the area of the rectangle. This means that any value of type Rectangle
can be used wherever a value of type Shape
is expected.
Now time to handle the error.
Error Handling:
Error handling in Go is typically done using the built-in error
type, which is a simple interface type that represents an error condition. To return an error from a function, simply return a value of type error
along with any other return values. For example:
In this example, the divide
function takes two int
parameters, a
and b
, and returns an int
result and an error
value. If b
is equal to 0
, the function returns a result of 0
and an error value created using the fmt.Errorf
function, which returns a new error with a formatted error message. If b
is not equal to 0
, the function returns the result of the division and a nil
error value, which indicates that no error occurred.
To check the error value returned by a function, simply test it against nil
:
In this example, the divide
function is called with the arguments 10
and 2
. If an error occurs, the error message is printed, otherwise the result of the division is printed.
Huhhh. Continually interested in it? umm, You have enough patience, must say. I won’t have so. You can now inquire further with chatGTP.
Finally, Take a bite of the simple Golang program that concludes by expressing gratitude for your patience.
To run this program, save the code to a file with a .go
extension (e.g. hello.go
) and run the following command in the terminal and have my gratitude.
Bye Bye for Toady.
