Guessing Game Collection

A collection of the number guessing game in different languages - weekly update ;)

Aimed to help me explore & touch new languages & technologies. Writing a simple game definitely cannot exploit the full advantages / disadvantages of a language, but should be a good start towards learning its pipeline of development and basic syntax.

Progress List

System programming languages:

• C
• C++
• Rust
• Go

Common scripting languages:

• Python
• Ruby
• Julia
• R

Java & its variants:

• Java
• Kotlin
• Dart

Web scripting languages (with sample page in HTML/CSS):

• JavaScript
• TypeScript
• PHP

Other app development:

• Swift
• Objective-C
• C#

Lisp & its dialects:

• Common Lisp
• Scala
• Scheme
• Clojure

Erlang & its variants:

• Erlang
• Elixir

Assembly:

• MIPS
• RISC-V
• x86
• ARM
• WebAssembly

Testing

Run the tester with Python3:

$ python3 test-all.py

This will give comprehensive tests for all language versions defined in test-all.py. Outputs will be strictly matched.

Expected Behavior

Normal behavior is a guessing game where the player tries to guess a random integer between 1 to 100.

Welcome to Guanzhou's guessing game!
Enter an int ∈ [1, 100], or 'q' to quit: 50
  Your guess is... Too large!
Enter an int ∈ [1, 100], or 'q' to quit: 25
  Your guess is... Too large!
Enter an int ∈ [1, 100], or 'q' to quit: 12
  Your guess is... Too large!
Enter an int ∈ [1, 100], or 'q' to quit: 6
  Your guess is... Too small!
Enter an int ∈ [1, 100], or 'q' to quit: 9
  Your guess is... Too large!
Enter an int ∈ [1, 100], or 'q' to quit: 7
  Your guess is... Too small!
Enter an int ∈ [1, 100], or 'q' to quit: 8
  Your guess is... Correct!
You win! Congrats ;)
<Game stats>
  You tried: 50 25 12 6 9 7 8
  In total 7 tries used.

Binary search should be the best strategy overall, but you can get lucky sometimes ;)

Robustness requirements under boundary conditions are defined as the following:

# Invalid input.
Enter an int ∈ [1, 100], or 'q' to quit: e
WARN: not a valid integer. Try again...

# Out-of-range input.
Enter an int ∈ [1, 100], or 'q' to quit: -141
WARN: valid input ∈ [1, 100]. Try again...

# Allow leading & trailing whitespaces.
Enter an int ∈ [1, 100], or 'q' to quit:   50 \t
  Your guess is... Too large!

# Empty input.
Enter an int ∈ [1, 100], or 'q' to quit:        # Directly display a new prompt.
Enter an int ∈ [1, 100], or 'q' to quit:

# Start with 'q'.
Enter an int ∈ [1, 100], or 'q' to quit: qewe   # Treat as quit signal as well.
Sad to see you go :(

All language versions must satisfy this specification.
