Move from variables to addresses, then read and write pointer code safely in modern C++
4 sections · 8 lessons
Define pointers as addresses, then read declaration, initialization, dereferencing, and the core symbols that make pointer code work.
2 lessonsCompare references and pointers, then examine arrays, pointer arithmetic, and safer iteration with `std::span` and iterators.
2 lessonsTrace object lifetime, dangling pointers, null pointers, defensive checks, and smart pointers as safer ownership tools.
3 lessonsConsolidate the pointer mental model and apply the main safety rules with a real-code checklist.
1 lessonPointers are one of the first places where programming stops being just values and starts touching memory directly. This course builds a clear, beginner-friendly mental model of what pointers are, how they relate to variables, and how modern C++ uses them safely. By the end, you will be able to read pointer syntax, compare pointers with references, recognize null and dangling cases, and understand when smart pointers are the better choice.
The course covers pointer basics, declaration, initialization, dereferencing, and the meaning of `*`, `&`, and `nullptr`. It also covers references versus pointers, arrays and pointer arithmetic, lifetime and invalid pointers, null checks, and smart pointers for ownership in modern C++.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
