Dynamic type languages versus static type languages
...y of the interpreter to deduce type and type conversions makes development time faster, but it also can provoke runtime failures which you just cannot get in a statically typed language where you catch them at compile time. But which one's better (or even if that's always true) is hotly discussed in...
How to compute the sum and average of elements in an array?
... @BramVanroy Short story: No, it does not set 'l' every single time. Long story: DanD's solution is to improve the performance/speed, because checking the length of an array every single iteration is slower than actually storing the length in a local variable and referencing it each iter...

Why do objects of the same class have access to each other's private data?
...r-object basis.
Access control in C++ is implemented as a static, compile-time feature. I think it is rather obvious that it is not really possible to implement any meaningful per-object access control at compile time. Only per-class control can be implemented that way.
Some hints of per-object co...
Optimal number of threads per core
