C++ Projects: Snake Game Hello everyone, welcome back to the blog. Today we will build the classic Snake Game using C++. This program offers a console-based version of the classic game where the snake moves around, eating food to grow in size. If the snake collides with itself or hits the walls, the game ends. Skills Used Arrays – Used for tracking the body of the snake. Loops – Used for continuously running the game. Conditional statements – Used for handling movements, collisions, and game-over logic. Handling input – Detecting key presses for controlling the snake. The Code to Build the Project #include <iostream> #include <conio.h> // For keyboard input #include <windows.h> // For sleep function using namespace std; // Global variables const int width = 20; const int height = 20; int x, y, foodX, foodY, score; int tailX[100], tailY[100]; // Snake's tail coordinates int nTail; // Current length of tail bool gameOver; enum Direction { STOP = 0, L...

C++ Projects: Password Manager Welcome to the series of C++ projects. Here, I will guide you on how to build useful applications and systems using your C++ skills. These projects won't be extremely easy or beginner-friendly, but I will do my best to explain them in the clearest way possible. Let's build something great! This project securely manages passwords by storing and retrieving them for different accounts. Passwords are encrypted before being saved to a file, and a master password is required for access. Skills Used File Handling: Reading and writing passwords to a file. Encryption and Decryption: Using the Caesar cipher to secure passwords. Conditional Statements: Handling account searches and invalid passwords. String Manipulation: Encrypting and decrypting stored passwords. Code to Build the Password Manager #include <iostream> #include <fstream> #include <string> #include <map> using namespace std; // Simple encryption funct...

C++ Mini Projects: ATM Simulator This is an ATM simulator that requires users to log in with a PIN, perform transactions, and log out—just like a real ATM machine. Let's build the software inside the ATM! Skills Used Handling files: Logging all transactions to a file Conditional statements: Managing invalid inputs and account rules Functions: Breaking down the program into smaller, manageable parts Loops: Navigating the menu and handling repeated PIN attempts Input and output management: Managing user inputs and displaying outputs The Code to Build the Project #include <iostream> #include <fstream> #include <string> #include <iomanip> using namespace std; // Function prototypes bool login(int correctPIN); void displayMenu(); void checkBalance(double balance); void deposit(double &balance, ofstream &logfile); void withdraw(double &balance, ofstream &logfile); void logTransaction(ofstream &logfile, const string &type, doubl...

C++ Mini Projects: Traffic Light Simulator This is a simulation for a traffic light system with time durations for red, green, and yellow lights. The program includes a feature for pedestrians to request crossing. Let's create this useful application. Skills Used Loops To repeat the normal cycle of lights Managing Time this_thread::sleep_for , for delays Conditional Statements For pedestrian requests and changing the light sequence The Code to Build the Project #include <iostream> #include <thread> #include <chrono> #include <string> using namespace std; // Function to display the traffic light void displayLight(const string& lightColor, int duration) { cout << "\nLight: " << lightColor << " (" << duration << " seconds)\n"; for (int i = duration; i > 0; --i) { cout << "\rTime remaining: " << i << " seconds" << flush...

C++ Mini Projects: Online Quiz Creator With the help of this project, users can create, save, and implement quizzes. The quizzes contain multiple-choice questions, and the program calculates scores after a user attempts a quiz. Quizzes are reusable as they are stored in files. So let's build it. Skills Used File handling : To save and load quiz data. Vectors : For storing and handling quiz data. Conditional statements : For checking answers and calculating scores. Functions : For organizing code to create, take, and manage quizzes. The code to build the desired project #include <iostream> #include <fstream> #include <vector> #include <string> #include <sstream> using namespace std; // Structure to represent a question struct Question { string questionText; vector<string> options; int correctAnswer; // Index of the correct answer (0-based) }; // Function to display the main menu void displayMenu() { cout << "...

C++ Mini Projects: Recipe Book Hey guys, today we are going to build a recipe book project. This is a console-based, simple recipe book where users can not only search and view but also add, update, or delete recipes in the system. Each recipe will contain information such as the name, ingredients, and step-by-step method. All data will be stored in files for persistence. So what are we waiting for? Let's jump in and get started! Skills Used File Handling Used for saving the recipes and retrieving them for later use. Vectors Used for storing and manipulating different recipes efficiently. Functions Used for managing code by dividing it into reusable parts. Strings Used for names of recipes, ingredients, and step-by-step instructions. The Code to Build the Project #include <iostream> #include <fstream> #include <vector> #include <string> #include <sstream> using namespace std; // Structure to store recipe details struct Recipe { string...

C++ Mini Projects: Calendar Application Hey guys! Today, we are going to build something simple yet useful using our skills in C++. As the name suggests, it's going to be a calendar application. We all know what a calendar does, so let's jump right in and start building! Skills Used Input of Month and Year : Users will input the desired month and year. Displaying the Calendar : The application will generate a properly formatted calendar for the given input. Highlighting Weekends : Weekends will be enclosed in parentheses. Marking Important Dates : Users can specify important dates to be highlighted. The Code to Build the Project #include <iostream> #include <iomanip> // for setw #include <vector> using namespace std; bool isLeapYear(int year) { return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0); } int getDaysInMonth(int month, int year) { if (month == 2) { return isLeapYear(year) ? 29 : 28; } if (month ...

C++ Mini Projects: Expense Splitter This is a very handy app used to split expenses between people. When multiple individuals contribute money for a shared expense, this C++ expense splitter helps determine each person's fair share. Isn't that interesting and useful? Let's dive in and build one! Skills Used Handling multiple participants : The program can accommodate any number of people. Precision calculations : Ensures accurate financial division. Displaying results with two decimal places : Uses setprecision and fixed to format output. The Code to Build the Project #include <iostream> #include <vector> #include <string> #include <iomanip> // for fixed and setprecision using namespace std; struct Person { string name; double amountPaid; }; void calculateExpenses(const vector<Person>& people) { double total = 0.0; int numPeople = people.size(); // Calculate total expense for (const auto& per...

C++ Mini Projects: Hangman Game Guys, I'm back with another cool project—the Hangman game! This one is going to be pretty interesting, and I want to warn you beforehand that it's not one of the easiest in the series. However, since we have built many projects by now, we should be able to tackle this one as well. Just focus on the project, and if there's anything you're confused about, feel free to ask. Let's go! The Code to Build the Project cpp Copy code # include <iostream> # include <string> # include <vector> # include <cstdlib> # include <ctime> # include <algorithm> using namespace std; // Function to display the current state of the word void displayWord ( const string& word, const vector< bool >& guessed) { for ( size_t i = 0 ; i < word. size (); ++i) { if (guessed[i]) { cout << word[i] << " " ; } else { cout <...
