Why is it bad to use namespace std? I know you can use using std::cout or anything else for that matter or just not use anything like and just have std::(whatever) however why would be bad just to use the whole
In 32-bit, the main calling convention in C is cdecl. The 16 bytes of function arguments are pushed onto the stack in reverse order, as well as an extra pointer. This extra pointer points to 8 bytes of stack-allocated space and is used to store the return value. This causes everysolve...

Using thethiskeyword totally transforms the bytecode! Rather than usinggetlex, the bytecode is now identical to thenum = this.valbytecode except for referencing the parent class instead of the base class ingetproperty. Does the compiler do this when we use thesuperkeyword? Let’s look: ...
