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.

ChatGPT Response

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?

Golang Syntax

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:

Golang variable
Golang Variable

Is there any more to say about variables? Isn't the answer a resounding no?

Then proceed to ‘Types’.

Golang Types

Golang also supports user define types like as —

Control Structure?

There are various types of control structures. Let's talk about them now.

Golang control flow structure

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.

Golang function

Let’s dive into golang pointer.

Pointer:

Pointer holds the memory address of a value.

Syntax:

Golang pointer syntax

Example:

Golang pointer 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.

Golang program for gratitude

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.
