Creating a Hangman game in C++ is a fun and beginner-friendly project to learn C and C++ programming language. This guide will walk you through the game’s rules, work, and implementation to bring this classic word-guessing puzzle to life.
What is hangman game in C++?
Hangman game is a word-guessing game where you guess a hidden word one letter at a time. Each wrong guess adds to a stick-figure drawing of a man hanging. Guess the word in time, and you win!
Features of this Hangman Game:
- Random Word Selection: A random fruit name is chosen from a predefined list as the hidden word.
- Player Interaction: The player can guess letters with prompts and feedback provided for each guess.
- Tracking Guesses: Correct and incorrect guesses are tracked, ensuring players don’t repeat guesses.
- Limited Attempts: Players have a fixed number of attempts to guess the word correctly.
- Visual Feedback: A representation of the hangman game figure is displayed with each incorrect guess.
Programming Concepts Involved
Randomization
Randomization helps pick a word from a predefined list. By seeding the rand() function with the current time using srand(), the program ensures a new word is selected each time it runs.
vector wordPool = { "apple", "banana", "cherry", "grape", "kiwi" };
int randomIndex = rand() % wordPool.size();
return wordPool[randomIndex];Loops and Conditionals
The loops process player guesses and conditionals to determine if a guess is correct or incorrect. The game continues until the player wins by guessing the word or loses by exhausting their attempts.
while (remainingTries > 0) {
// Prompt for user guess
// To Check if the guess is correct or incorrect
// Update game state accordingly
}String Manipulation
The hidden word is represented as a string, with underscores (_) displaying unguessed letters. Correct guesses replace the underscores with the corresponding letters.
