Introduction to Go

Go (or Golang) is a statically typed, compiled programming language designed by Google. Known for its simplicity, concurrency support, and performance, Go is ideal for building modern software that is efficient and scalable.

What is Go Best Used For?

• Building web servers and APIs.
• Developing cloud-native and microservices-based applications.
• Creating high-performance tools for system-level programming.
• Writing concurrent programs with simple and powerful concurrency primitives.

Example Go Program

This program demonstrates variables, a loop, and output.

package main

import "fmt"

func main() {
    // Declare variables
    greeting := "Hello, Go Programmer!"
    count := 5

    // Display greeting
    fmt.Println(greeting)

    // Loop through numbers 1 to count
    for i := 1; i <= count; i++ {
        fmt.Printf("Iteration: %d\n", i)
    }

    // Print completion message
    fmt.Printf("Loop completed! Total iterations: %d\n", count)
}

Explanation:

1. Variables: greeting is a string variable, and count is an integer specifying the loop limit.
2. Loop: The for loop runs from 1 to count, printing the current iteration using fmt.Printf.
3. Output: The program outputs a greeting, the iteration messages, and a final completion message.

Sample Output:

Hello, Go Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
