WebApr 8, 2024 · C++ gets the defaults wrong. C++ famously “gets all the defaults wrong”: switch cases fall through by default; you have to write break by hand. Local variables are uninitialized by default; you must write =0 by hand. (In a just world, there’d be loud syntax for “this variable is uninitialized,” and quiet syntax for “this variable is ...
