What is the use of passing an argument by value?
Passing an argument by value means that the method that receives the argument can not change the value of the argument. Passing an argument by reference means that the method that receives the argument can change the value of the incoming argument, and the argument may be changed in the orignal calling method.
What is the name given to the technique whereby a function argument can be modified by passing a pointer to the argument?
Call_by_reference
What argument passes in a method that will reference the content and can change the variable in the method?
That is called passing an argument by reference.
What is the difference between parameters and arguments in VB?
In programming languages, a parameter and an argument are the same thing; there is no actual difference between the two. Although a few languages do differentiate between an actual argument and a formal argument by calling one a parameter and the other an argument (or vice versa), the terms are universally interchangeable. That is; there is no single definition that applies to any one language, including Visual Basic. The language may have a convention, but there's no reason to follow that convention. Personally, I prefer the term argument and use the terms formal argument and actual argument whenever I need to specifically differentiate one from the other. In this way I can refer to them in a consistent but language-agnostic manner. Only a Pedant would argue that the terms parameter and argument have a specific meaning to a specific language, even when the creators of that language use the terms interchangeably themselves. To clarify, an actual argument is the argument being passed to a function while a formal argument is the argument that is used by the function. The two will always have the same value, but they are not the same argument. For instance, consider the following function definition: f (int a) { print a*2 } Whether we regard 'a' as being a parameter or an argument is immaterial -- it is a formal argument or formal parameter, whichever you prefer. The meaning is clarified by using the word "formal". Now consider the calling code: b = 42 f (b) Here, b is the actual argument (or actual parameter) being passed to the function f. Note that a and b are not the same variable or reference. That alone means there is no reason to differentiate them; the meaning of argument or parameter is implied by the context alone. It doesn't matter whether the function uses pass by value or pass by reference semantics. When passing arguments by value, a is simply a copy of b (independent variables with the same value). When passing by reference, a refers to the same memory address as b (a is an alias for b). In either case, the function uses the formal argument named a while the calling code uses the actual argument named b. In other words, the names are only accessible from within the scope in which they are declared, even if they refer to the same memory address. Of course, a function may pass one of its formal arguments to another function. Thus with respect to the calling function, its formal argument becomes an actual argument to the function being called.
Where to use overloading?
Default arguments are often considered to be optional arguments, however a default argument is only optional in the sense that the caller need not provide a value for it. The function must still instantiate the argument and must assign the appropriate value to it so, insofar as the function is concerned, the argument is not optional. To implement a function with a truly optional argument, we can define two overloads of that function, one that accepts the optional argument (without specifying a default value) and one that does not accept the argument. In this way we can define two different implementations, one that uses the argument and one that does not. void f (); // implementation that does not use the argument void f (int); // implementation that does use the argument In many cases, a default argument incurs no significant overhead over that of overloading. Thus we'd only use overloading to implement an optional argument where there is a significant overhead incurred by a default argument. Even so, we must also be aware that by eliminating the overhead within the function itself we may simply be passing that overhead back to the callers, because some or all of them would then have to decide which overload to call, resulting in code duplication that would likely be best handled by the function itself.
