helper functions as static functions or procedural functions?
Category : Programming Languages

i wonder if one should create a helper function in a class as a static function or just have it declared as a procedural function?


i tend to think that a static helper function is the right way to go cause then i can see what kind of helper function it is eg. Database::connect(), File::create().


what is best practice?

Operator Functions as Member Functions and Nonmember Functions
Category : Programming Languages

I am very confuse in getting the idea of operator overloading as a member and non member function.


What do we actually mean, when we overload operator as a non-member function and similarly what do we mean when we overload operator as a member fuctions. Although I know that the non-member functions are the friend functions.

I have a function called by many other functions. Is there an easy way to find where any of it's calling functions (or their calling functions) ar
Category : Programming Languages

I have a function which is called explicitly by 4 other functions in my code base. Then in turn each of these functions is called by at least 10 other functions throughout my code. I know that I could, by hand, trace one of these function calls to the main function of my program (which has 30 function calls) but it seems like this would be a better job for the computer. I just want to know w

Haskell Lambda functions — two seemingly equivalent functions, one works and the other is erroneous
Category : Programming Languages

This Lambda function returns 1:


(x y -> 1) 1 p

where p = (x y -> 1)


Okay, that makes sense to me -- the Lambda function returns 1, independent of its arguments.


Now, this Lambda function generates an error (infinite type error):


(x y -> x y x) p 1

That doesn’t make sense to me. If that fu

How to write a wrapper over functions and member functions that executes some code before and after the wrapped function?
Category : Programming Languages

I'm trying to write some wrapper class or function that allows me to execute some code before and after the wrapped function.


float foo(int x, float y)
{
return x * y;
}
BOOST_PYTHON_MODULE(test)
{
boost::python::def("foo", <somehow wrap "&foo">);
}

Ideally, the wrapper should be generic, working for funct

Is there a way to see what Javascript functions (the name of the functions) execute in real time in Chrome's Inspector?
Category : Javascript

For example, pretend there is Javascript code that will execute someFunction() when a button is clicked and I click that button. I wonder if there is some way to see that someFunction() was just executed. Is there a way to see what functions are executed in Chrome in real time?


If it is the Profiles tab in the inspector that does the trick, how exactly do y

“Nested functions are disabled, use -fnested-functions to re-enable”
Category : Programming Languages

I want to use this code (from my last question (thanks Adam)),


bool AllDigitsIdentical(int number)
{
int lastDigit = number % 10;
number /= 10;
while(number > 0)
{
int digit = number % 10;
if(digit != lastDigit)
return false;
number /= 10;
}
return true;
}

Do C# static functions perform better than nonstatic functions, beyond reduced memory usage?
Category : C & C++ & C#

I assume that public or private static targets must have reduced memory usage, due to the fact that there is only one copy of the static target in memory.


It seems like because a method is static that might make the method a potential point for further optimization by the CLR compiler beyond what is possible with a non-static function. Just a
