Puzzle Lock is a small interactive terminal game written in C.
The goal is to guess a hidden 3-digit lock code using hints after each attempt.

This project is a simple logic-based guessing game inspired by lock-code puzzles.

The program randomly generates a 3-digit secret code.
After each guess, the player receives feedback showing how many digits are correct and whether they are in the correct position.

• Random 3-digit secret code
• Supports leading zeros such as 042
• Limited number of attempts
• Input validation
• Hint system
• Terminal-based gameplay
• Clean and simple C implementation

The secret code contains exactly 3 digits.

After each guess, the program gives two hints:

• Right place: correct digit in the correct position
• Wrong place: correct digit but in a different position

Example:

Secret code: 123
Guess: 132

Hint: 1 right place, 2 wrong place
