## Go Cheatsheet

Go is a programming language that is designed for simplicity, efficiency, and concurrency. Here's a quick overview of its unique features and some code blocks for common tasks.

### Variables

Declare variables using the `var` keyword. Go is a statically typed language, but it can infer the data type of a variable from its value.

x := 10

c := 'a'

f := 3.14

### Functions

Functions in Go are declared using the `func` keyword. They can take parameters and return values.

func add(a int, b int) int {

return a + b

}

### Loops

Go supports `for` and `while` loops for iterating over arrays or performing a task a certain number of times.

numbers := []int{1, 2, 3, 4, 5}

for _, number := range numbers {

fmt.Println(number)

}

i := 0

for i < len(numbers) {

fmt.Println(numbers[i])

i++

}

### Conditionals

Use `if` statements to execute code based on a condition. `else if` and `else` statements can be used to handle multiple conditions.

x := 10

if x > 0 {

fmt.Println("x is positive")

} else if x < 0 {

fmt.Println("x is negative")

} else {

fmt.Println("x is zero")

}

### File Manipulation

Go provides built-in support for file manipulation, including reading and writing files, and interacting with the file system.

package main

import (

"fmt"

"io/ioutil"

"os"

)

func main() {

data, err := ioutil.ReadFile("/path/to/file.txt")

if err != nil {

fmt.Println("Error reading file")

return

}

fmt.Println(string(data))

err = ioutil.WriteFile("/path/to/file.txt", []byte("New contents"), 0644)

if err != nil {

fmt.Println("Error writing file")

return

}

err = os.Remove("/path/to/file.txt")

if err != nil {

fmt.Println("Error deleting file")

return

}

fmt.Println("File deleted successfully")

}
