Python Example of function as argument: Here, we are going to learn how we can pass a function as an argument in Python?
The built-infilterfunction accepts two things as an argument: afunctionand aniterable. >>>help(filter)| filter(function or None, iterable) --> filter object|| Return an iterator yielding those items of iterable for which function(item)| is true. If function is None, return the items that...

Passing Arrays as Function Arguments in C - If you want to pass an array to a function, you can use either call by value or call by reference method. In call by value method, the argument to the function should be an initialized array, or an array of fix
Objects such as lists and dictionaries are passed by object reference too, which is similar to the way C passes arrays as pointers—mutable objects can be changed in place in the function, much like C arrays. Of course, if you’ve never used C, Python’s argument-passing mode will be ...
optimizing over all non-keyword-only arguments (which keeps compatibility with the case of "standard" optional arguments, which are also optimized over), or throwing a more explicit error (because there isn't much to do anyways if the function has a keyword-only argument without a default ...
