Frequently Asked Questions
How does this C / C++ billing system work?
Customer master + invoice generation. Compute totals with discount/tax. Print invoice to console or file. Foundation for retail mini-project.
What compiler do I need to run this C or C++ project?
For C: gcc (GNU Compiler Collection) or MinGW (Windows). For C++: g++. IDE options: Code::Blocks (lightweight, built-in compiler), Dev-C++ (classic Philippine BSIT favorite), Visual Studio Code with C/C++ extension, CLion (paid). To compile from terminal: gcc program.c -o program (for C) or g++ program.cpp -o program (for C++), then run with ./program (Linux/macOS) or program.exe (Windows).
How do I run this C / C++ project?
Open the .c or .cpp file in your IDE (Code::Blocks, Dev-C++, VS Code). Click Build (or press F9), then Run (or press F5). From terminal: navigate to project folder, run gcc/g++ command above, then ./program. If using file storage, make sure the data file (e.g. records.txt) is in the same folder as the executable.
Can I use this C / C++ project for a BSIT capstone or thesis?
C/C++ projects are usually accepted for 1st-2nd year mini-projects or as building blocks. For a full capstone you would typically pair them with a more interactive frontend (e.g. wrap C++ logic with a Java/Python/PHP frontend, or extend to GTK/Qt for a real GUI). Standalone console C++ capstones are accepted by some panels but rare in 2026.
Why am I getting ‘undeclared identifier’ or ‘cannot find header’ errors?
Three common C/C++ issues: (1) Missing #include directive, e.g. #include
Where can I find more C or C++ projects with source code?
