// EXERCISE: Moodly #2
|
|
//
|
|
// This challenge is based on the previous Moodly challenge.
|
|
//
|
|
// 1. Display the usage if the username or the mood is missing
|
|
//
|
|
// 2. Change the moods array to a multi-dimensional array.
|
|
//
|
|
// So, create two inner arrays:
|
|
// 1. One for positive moods
|
|
// 2. Another one for negative moods
|
|
//
|
|
// 4. Randomly select and print one of the mood messages depending
|
|
// on the given mood command-line argument.
|
|
//
|
|
// EXPECTED OUTPUT
|
|
//
|
|
// go run main.go
|
|
// [your name] [positive|negative]
|
|
//
|
|
// go run main.go Socrates
|
|
// [your name] [positive|negative]
|
|
//
|
|
// go run main.go Socrates positive
|
|
// Socrates feels good 👍
|
|
//
|
|
// go run main.go Socrates positive
|
|
// Socrates feels happy 😀
|
|
//
|
|
// go run main.go Socrates positive
|
|
// Socrates feels awesome 😎
|
|
//
|
|
// go run main.go Socrates negative
|
|
// Socrates feels bad 👎
|
|
//
|
|

|
|
// Socrates feels sad 😞
|
|
