cpp projects for beginners
1. Calculators (Math, Tax, Physics, Chemistry, etc.) to get a feel of the scientific and basic uses for C++
2. Database (Be creative, use user input and textfile I/O)
3. Any CLI games (Helps with OOP and algorithmic thinking)
4. Mock Banking/Transaction programs
5. Applets (Innovate!)
6. Huffman Encoding Algorithm (It's an amazing project trust)
7. Credit card verifier (found it during CS50, it's a good one)
Try using the concepts you're learning in school (if you're in school) to apply them in a C++ program, ideally something with some input/output and computations involved
