C++
C++ has a reputation for difficulty that mostly comes from memory. These articles make ownership concrete — what a pointer holds, what a reference cannot do, when the STL already solved your problem — so the language stops feeling adversarial.
Memory and pointers
- C++ Smart Pointers: unique_ptr, shared_ptr, weak_ptr shared_ptr is not a garbage collector. Two objects that hold shared_ptr to each other never reach zero, their destructors never run, and the memory leaks in silence. Tutorial · 12 min read · August 6, 2026
- References vs Pointers in C++: Which to Use When for (auto s : names) copies every string in the vector on every pass, and the compiler will not say a word. Here is when to use a reference, a pointer, or neither. Comparison · 11 min read · August 6, 2026
- Stack vs Heap Memory: Where Your Variables Live Deep recursion is not slow, it is fatal. The stack is a fixed block handed to your thread at birth, and a single large local array can exhaust it in one line. Tutorial · 12 min read · August 6, 2026
- Segmentation Fault in C++: Causes and How to Debug It The program crashes with three words and no line number. These are the six causes, and the tools that point straight at the offending line. Tutorial · 10 min read · August 6, 2026

The standard library
- C++ STL Guide: Containers, Iterators and Complexity std::map is not a hash table, and writing m[key] to check a key silently inserts it. Two facts that change how your STL code behaves and what it costs. Tutorial · 12 min read · August 6, 2026
