Can you pass an object to a function as an argument?
The objects of a class can be passed as arguments to member functions as well as nonmember functions either by value or by reference. When an object is passed by value, a copy of the actual object is created inside the function. This copy is destroyed when the function terminates.
How do you pass an object as an argument in Python?

What does it mean to pass arguments in Python?
Correctly speaking, Python uses a mechanism, which is known as “Call-by-Object”, sometimes also called “Call by Object Reference” or “Call by Sharing”. If you pass immutable arguments like integers, strings or tuples to a function, the passing acts like call-by-value.
Can you pass a function as an argument in JavaScript?
In JavaScript, you can pass a function as an argument to another function (or assign it to a variable, etc.) but just referring to it by its name with no parentheses, like var func = foo or func(bar) (where foo and bar are functions).
When to use C style CString argument passing?
It does make sense in some cases to provide a C-style string. For example, there can be a situation where a called function is written in C and does not support objects. In this case, coerce the CString parameter to LPCTSTR, and the function will get a C-style null-terminated string.
What happens when you pass an integer to a function in Python?
If you pass immutable arguments like integers, strings or tuples to a function, the passing acts like call-by-value. The object reference is passed to the function parameters. They can’t be changed within the function, because they can’t be changed at all, i.e. they are immutable. It’s different, if we pass mutable arguments.
