IT-312 Software Development with C++.NET teaches students to design, implement, and test applications in the C++ programming language, using SNHU's virtual desktop infrastructure (VDI) for development work. Requiring IT-135 or IT-145 as a prerequisite, the course extends students' object-oriented programming foundation into a genuinely different, performance-oriented language than the scripting and Java-adjacent work covered earlier in the IT sequence.
A genuine second language after foundational OOP
The course introduces C++ specifically after students already have an object-oriented programming foundation from IT-145, letting them transfer core OOP concepts (classes, inheritance) to a new, syntactically different language rather than learning OOP and C++ syntax simultaneously.
Design, implementation, and testing as a complete cycle
IT-312 requires students to genuinely design, implement, AND test their C++ applications, teaching the full software development cycle rather than just writing code without verifying it works correctly.
Key topics in IT312
- C++ programming language fundamentals
- Application design in C++
- Implementation and testing
- Virtual desktop infrastructure development
- Transferring OOP concepts across languages
- Software development lifecycle practice

Worked example: transferring OOP concepts to a new language
- Learning in isolation: Learning C++ syntax and object-oriented concepts simultaneously from scratch
- IT-312's approach: Applying an already-established OOP foundation (from IT-145) to the specific syntax and conventions of C++
- Lesson: IT-312 teaches that genuine programming competency includes this ability to transfer core concepts across different languages, not relearning OOP fundamentals from zero each time

Frequently asked questions
C++ combines object-oriented programming concepts with additional complexity around memory management and performance-oriented syntax, and attempting to learn both OOP fundamentals and C++'s specific complexities simultaneously would be significantly harder than transferring an already-established OOP foundation into this new language. IT-312's prerequisite ensures students arrive with the conceptual OOP groundwork already solid, letting the course focus on C++'s specific syntax and practices rather than re-teaching object-oriented fundamentals.
Code that runs without errors isn't necessarily code that behaves correctly under all the conditions it will actually face, and testing is what verifies a program genuinely meets its design requirements rather than just appearing to work in a quick check. IT-312 requires this full design-implement-test cycle because professional software development depends on this verification step, and skipping it would leave students without a genuinely complete picture of the development process.
