I created this project when I started learning from the book Programming: Principles and Practice Using C++ (3rd Edition) by Bjarne Stroustrup.
It mainly contains example code from the book and solutions I wrote to solve its drill and exercises.
Sample programs:
Game Bulls and Cows (from exercise 12 of chapter 4):

Simple calculator (from chapter 6):

Design and implement classes: Book, Patron, Library, Date, Money (from exercises of chapter 8):

Add the commands "from" and "to" to the simple calculator from chapter 6,
and enable it to take input from a file and output results to another file (from exercise 25 of chapter 9):

Superellipses drawn by using the GUI library provided by the book (from exercise 12 of chapter 10).
