Explanation / Answer

package main

import (

"fmt"

"flag"

"strings"

"os"

"strconv"

"math"

"image"

"image/color"

"image/png"

"math/cmplx"

)

var myImage = image.NewRGBA(image.Rect(0, 0, 200, 200))

var customColor color.Color

func main() {

// use of fmt package

fmt.Println("Use Of fmt package")

// use of flag package

wordPointer := flag.String("WORD", "anyword", "a string")

numberPointer := flag.Int("NUMBER", 189, "an int")

flag.Parse()

fmt.Println("WORD:", *wordPointer)

fmt.Println("NUMBER:", *numberPointer)

// use of strings package

fmt.println(strings.ToUpper("chegg"))

// use of os package

os.Mkdir("chegg",0777)

// use of strconv package

s := strconv.Atoi("-42")

fmt.printf("%d" , s)

// use of math package

fmt.Printf("%f", math.Acos(0))

// use of image , image/colour , image /png

customColor = color.RGBA{255, 0, 0, 255}

HLine(20, 30, 90)

customColor = color.RGBA{0, 255, 0, 255}

Rect(20, 20, 90, 60)

fp := os.Create("myImage.png")

defer fp.Close()

png.Encode(fp, myImage)

// use of math/cmplx

fmt.Printf("%.2f", cmplx.Exp(2i*math.Pi)+3)

}
