Best golang program to explain every concept.

How to write basic golang program with all logics example 

Sure, here is an example of a basic Golang program that demonstrates some fundamental programming concepts:

go

Copy code

package main

import (

 "fmt"

)

func main() {

 // Variables

 var x int = 5

 y := 10

 // Conditional statements

 if x > y {

  fmt.Println("x is greater than y")

 } else {

  fmt.Println("y is greater than x")

 }

 // Looping

 for i := 0; i < 5; i++ {

  fmt.Println(i)

 }

 // Functions

 sum := addNumbers(x, y)

 fmt.Printf("The sum of %d and %d is %d\n", x, y, sum)

}

func addNumbers(a int, b int) int {

 return a + b

}

Let's go through each component of this program step by step:

The first line package main declares that this is the main package of the program. The main package contains the entry point of the program, which is the main function.

import ("fmt") imports the fmt package, which provides functionality for printing to the console.

func main() is the entry point of the program. All the logic of the program will be contained within this function.

var x int = 5 declares a variable x with the type int and initializes it to 5.

y := 10 declares a variable y and initializes it to 10. The type of y is inferred to be int by the Go compiler.

if x > y { ... } else { ... } is a conditional statement that checks if x is greater than y. If it is, the program prints "x is greater than y", otherwise it prints "y is greater than x".

for i := 0; i < 5; i++ { ... } is a loop that iterates 5 times and prints the value of i to the console on each iteration.

func addNumbers(a int, b int) int { ... } is a function that takes two integer arguments a and b, adds them together, and returns the result.

sum := addNumbers(x, y) calls the addNumbers function with x and y as arguments, and stores the result in the sum variable.

fmt.Printf("The sum of %d and %d is %d\n", x, y, sum) uses the Printf function from the fmt package to print the sum of x and y to the console.

That's it! This program demonstrates some of the basic concepts of programming in Go, such as variable declarations, conditional statements, looping, functions, and printing to the console.
