51 advanced C++ problems covering matrices, strings, recursion, file handling, and real projects — built on clean code and Divide & Conquer thinking.
This is Course 7 in the Programming Foundations Roadmap by Dr. Mohammed Abu-Hadhoud.
At this stage, the foundations were already in place:
- Algorithmic thinking from Levels 1 & 2
- Clean code and Divide & Conquer from the solutions course
- Advanced C++ from Level 2 (pointers, memory, file I/O, vectors)
Now came the next level of truth:
You don't become a programmer by learning more. You become one by practicing more.
This course delivers 51 carefully selected problems — harder than Level 2 — followed by two complete real-world projects.
2D array operations from the ground up: generating random and ordered matrices, summing rows and columns, transposing, multiplying two matrices, and checking matrix properties (identity, scalar, sparse, palindrome). Also covers finding intersected numbers across multiple matrices and extracting min/max values.
Character-level logic and string manipulation: Fibonacci series (iterative and recursive), case conversion, vowel detection and counting, word-level operations (split, join, trim, reverse, replace, remove punctuations), and function overloading for string utilities.
Record serialization and file-based data management: converting structs to lines and back, reading and writing client records, adding, finding, deleting, and updating clients by account number — the direct build-up to the projects.
A complete console-based banking system.
The problems from 45–51 were not isolated exercises — they were a direct build-up to this project.
Features:
- List all clients in a formatted table
- Add, delete, update, and search clients by account number
- Text file-based persistence using a custom separator format
- Soft-delete pattern before file rewrite
- Enum-driven menu navigation
The same bank system — extended with a full Transactions Menu.
New Features:
- Deposit funds into any account
- Withdraw with balance validation loop
- Total Balances screen with full bank sum
- Withdraw reuses the Deposit function with a negative amount — zero duplication
- Matrix operations and 2D array manipulation
- Recursive thinking (Fibonacci with recursion)
- String processing and character-level logic
- File I/O and record serialization
- Real-world system design through projects
- Clean code under sustained practice pressure
- The habit of attempting → analyzing → improving

Because experience is not given.
It is built — through repetition, difficulty, and reflection.
Course 8 — Algorithms & Problem Solving – Level 4
65 new problems. Harder. Larger. More realistic.
The foundation is solid.
The practice continues.
