🧮 Simple C Calculator

A basic calculator program in C that runs in the terminal.
It supports the following operations:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Modulo (%)

This project is a great starting point for beginners learning C programming, switch statements, and basic arithmetic operators.

⚠️ Error Handling

Division by Zero → Prints an error message instead of crashing.

Modulo by Zero → Prints an error message instead of crashing.

Invalid Operator → Prints "Error: Invalid operator."

📖 Concepts Covered

#include <stdio.h> → Standard I/O library

switch-case → Control flow in C

Typecasting → (int)n1 % (int)n2 for modulo operation

Error handling for invalid input

🎯 Number Guessing Game in C

A simple Number Guessing Game written in C where the computer randomly chooses a number between 1 and 100, and the player has to guess it within limited attempts.

---

📌 Features

• Random number generation using rand() seeded with current time.
• Player gets 10 attempts to guess the number.
• Hints provided:
  • Too high if the guess is larger than the number.
  • Too low if the guess is smaller than the number.
• Game ends when:
  • The player guesses correctly 🎉
  • OR runs out of attempts 😢

---

🖥️ How It Works

1. The program picks a random number between 1 and 100.
2. The user enters guesses one by one.
3. The game gives feedback after every guess.
4. The game ends when the number is guessed correctly or attempts are finished.

🎲 Dice Rolling Game (C)

A fun and simple command-line dice rolling game written in C.
Every time you roll, you get a random number between 1 and 6.
You can keep rolling until you decide to stop.

---

🚀 Features

• Generates a random dice roll (1–6) 🎲
• Lets you roll again with Y/y
• Option to quit with N/n
• Beginner-friendly project for learning loops, randomness, and user input

---

🖥️ How to Run

(On Windows use dice_game.exe)

📝 Example Gameplay scss Copy code Welcome to the dice rolling Game! you rolled 4 roll again(y/n): y you rolled 2 roll again(y/n): y you rolled 6 roll again(y/n): n Thanks for playing

📖 Concepts Covered

rand() and srand(time(0)) → random number generation

do { ... } while() loop → repeat until user quits

scanf(" %c", &choice) → handle user input

Basic control flow and loops in C

---

🎲 Dice Rolling Game in C (advanced model)

this is the second version of the dice rolling game eliminating y/n choice with a easier enter button

A simple command-line dice rolling game written in C.
Press ENTER to roll the dice, or type any other key and press ENTER to quit.
Perfect beginner project to practice loops, random numbers, and user input handling in C.

---

🚀 Features

• Roll a 6-sided dice 🎲
• Infinite rolls until you quit
• Random outcomes on every roll
• Simple and interactive terminal-based gameplay

---

📖 Concepts Covered

rand() and srand(time(0)) → random number generation

do { ... } while() loop → repeat until user quits

scanf(" %c", &choice) → handle user input

Basic control flow and loops in C

🔠 Guess the Letter Game (C)

A simple command-line guessing game written in C.
The computer randomly picks a letter between A and Z, and you have to guess it within a limited number of attempts.

---

🚀 Features

• Randomly selects a letter (A–Z) 🎯
• User-friendly hints:
  • "Too high!" → Your guess is later in the alphabet
  • "Too low!" → Your guess is earlier in the alphabet
• Maximum 8 attempts to guess correctly
• Case-insensitive input (e.g., a or A works the same)
• Beginner-friendly project for practicing loops, conditionals, random numbers, and character handling

---

📖 Concepts Covered

rand() and srand(time(0)) → Random letter generation

toupper() from <ctype.h> → Case-insensitive comparison

do { ... } while() loop → Multiple attempts until limit

Input handling with scanf()

Conditional logic (if, else if, else)

---

❌⭕ Tic Tac Toe in C

A simple Tic Tac Toe game written in C for two players.
Players take turns entering their moves until one wins or the game ends in a draw.

---

🚀 Features

• Two-player mode (X vs O)
• Displays the game board after every move
• Detects winners across rows, columns, and diagonals
• Declares a draw if the board is full
• Input validation (prevents overwriting cells)

---

📖 Concepts Covered

2D arrays (board[3][3]) to store the game board

Functions for board initialization, printing, and winner checking

Loops to keep the game running until a result

Conditionals for move validation and winner detection

Ternary operator to switch between players

---

🧠 Memory Game in C

A simple console-based memory game written in C language. The player must remember a sequence of random numbers and re-enter them correctly to progress through levels. The game continues until the player makes a mistake or successfully completes all levels.

---

📌 Features

Random sequence generation using rand().

Increasing difficulty with each level.

User-friendly prompts to enter the sequence.

Game over message with the correct sequence shown.

Cross-platform support for clearing the screen (cls for Windows, clear for Linux/macOS).

Maximum of 20 levels.

---

📂 Code Overview

Sequence generation: Generates random digits (0–9) using rand().

Display sequence: Shows the current level’s sequence for the user to memorize.

User input: Prompts the user to re-enter the sequence.

Validation: Compares input with the generated sequence.

Progression: Moves to the next level if correct, otherwise ends the game.

---

📖 Learning Concepts

This project demonstrates:

Loops (for, while)

Arrays

Random number generation (rand())

Conditional logic (if-else)

Functions from <stdio.h>, <stdlib.h>, and <time.h>
