printf with your own wrapper with metaprogramming/gcc format attribute for type checking

Why your viewpoint is so C++ driven

@手巴同事
你有冇覺得自己寫C++需要low level知識？
你有冇覺得pointer hard to understand？

diu, no chinese

手巴同事覺得兩個答案都係冇

狗衝c++了

手巴自己都覺得兩個答案都係冇

See手巴講pointer個po 簡單易明

手巴同事表示
array唔low level
pointer唔low level
uninitialized variable random value唔low level
stack overflow唔low level

btw Java都有stack overflow
uninitialized pointer上面call野會ub係關standard事唔關memory layout事

手巴自己黎講 low level係你要打開層abstraction先做到野
一般黎講 memory is a very large array of byte係常識 亦唔超出application programmer個level (application programmer本身要識array)
pointer亦唔超出application programmer個level (application programmer本身要識用array index)
你自己睇點syscall係你既事 application programmer用printf係唔駛睇的
