Intermediate Level C++ Project Ideas

1. Snake Game

This Snake Game project in C++ is a classic game that is easy to understand and enjoyable to play. This project gives players a sense of accomplishment when they reach higher levels. The code includes various functions and classes, such as a snake class that can be used to move the snake and a board class for creating the game’s playing field. The Snake game will be developed using open-source C++ libraries such as conio and various components such as classes, functions, and loops. As the level of the game increases, Object-Oriented Programming will be applied to make a more efficient coding architecture.

Technologies Required: C++ programming language, Object Oriented Programming (OOPS), Data Structures & Algorithms, Multithreading & Processes, Keyboard & Mouse Events, Timers & Clock.

2. Text Editor

A user can create, edit, save, and open text files using the text editor, a straightforward program. In addition to a user interface for the user to interact with, it uses classes and objects to store and alter the content. Basic text editing functions including copying, pasting, deleting, searching, and printing text are all available in the text editor. Text Editor is a simple application that is built into C++ programming language. We can use Graphical User Interface (GUI) Libraries such as QT, and GTK+ for creating a graphical user interface. Libraries such as Pango or Cairo are required to display text on the screen.

Technologies Required: C++ programming language, GUI Libraries, File I/O Library, Compression Libraries, Regular Expression Library.

3. Tic-Tac-Toe

Tic-Tac-Toe is a classic two-player game written in C++. In this game, each player takes turns placing Xs and Os on a 3×3 board, with the goal of getting three of their pieces in a row (horizontally, vertically, or diagonally). The game is won when a player gets three in a row, and it is a draw if the board is filled up without either player achieving that. The game board in Tic-Tac-Toe Project is represented by a two-dimensional array, and players engage in gameplay by entering moves into the console. If the move is valid, the game will then check the board to see if it is, and if so, it will switch turns between the two players. When one player collects three consecutive wins, or when the board is entirely filled, the game is over.

Technologies Required: C++ programming language, Object Oriented Programming (OOPS), GUI (Graphical User Interface), Data Structures, File Input/Output.

4. Minesweeper Game

Technologies Required: C++ programming language, OpenCV Library, Image Processing Library (NumPy, sci-kit-image).

8. OpenCV Project for Image Blur

In this project cvtColor inbuilt function in C++ is used that is used to convert one color space to another by using the color space conversion code. These codes are easily accessible and are predefined. The end result of this project will be a blurred version of the original image which we have given as Input.

Technologies Required: C++ programming Language, OpenCV Library for Image Processing, Computer Vision, and Image Processing Techniques.

9. OpenCV to play a Video
