10. About Time

Activity 10.01: Formatting a Date According to User Requirements

Solution:

  1. Create a file called Chapter_10_Activity_1.go and initialize it with the following code:
    package main
    import "fmt"
    import "time"
    import "strconv"
    func main(){
  2. Capture the following values: date, day, month, year, hour, minute, and second:
      date := time.Now()
      day := strconv.Itoa(date.Day())
      month := strconv.Itoa(int(date.Month()))
      year := strconv.Itoa(date.Year())
      hour := strconv.Itoa(date.Hour())
      minute := strconv.Itoa(date.Minute())
      second := strconv.Itoa(date.Second())
  3. Print the concatenated output:
      fmt.Println(hour + ":" + minute + ":" + second + " " + year + "/" + month   + "/" + day)
    }

    The expected output is as follows (note that this depends on when you run the code):

    15:32:30 2019/10/17
