Question
Why is C/C++ still relevant today despite being decades old?
Answer
Because its ubiquity, power, and raw speed make it indispensable for systems-level work that higher-level languages can't do.
| Reason | Examples |
|---|---|
| Ubiquity | Operating systems (Linux, Windows), device drivers, embedded/IoT |
| Power | Direct memory access, expressive yet terse syntax |
| Speed | Among the fastest languages, minimal runtime overhead |
C/C++ is the foundation for many "higher-level" tools:
- CPython (Python's interpreter) is written in C
- V8 (Chrome's JavaScript engine) is written in C++
- Most database engines, web servers, and game engines
The trade-off:
"With great power comes great responsibility."
C gives you direct hardware access, but it won't stop you from shooting yourself in the foot. No garbage collection, no bounds checking, no hand-holding.
