1. Pass-by-Value - The function argument variable is declared as pass-by-value, which works like an assignment statement assigning the value of the calling expression to the argument variable. In other words, when the function is called, the calling statement provides a variable (or an expres...
In C++ all arguments are passed to functions by value. In other words, a copy of the value is taken and that is what the function has to work with. If you want to modify the original value you must either pass a pointer or reference to the original value you wish to modify. Of cou...
Function to compare string lengths In the following program, twostringsare passed to compare() functions. In C, as string is an array of char data type. We usestrlen() functionto find the length of string which is the number of characters in it. ...

By default, LotusScript passes arguments to functions and subs by reference. If the argument is an array, a user-defined data type variable, or an object reference variable, you must pass it by reference. In most other cases, you use the ByVal keyword to
back one of the recorded values. The code would have to be aware of what the form is of the prompts for the two different functions in order to be able to figure out whether the prompt it was passed should be treated as a new request or else to return one of the previous values ...
In order to pass the value by reference, the "msdt_a1" is treated like any other value when passed to the functions. Therefore, you must declare the "msdt_a2" as reference types in the "swap()" function, which swaps the values of the two integer variables indicated by its arguments. ...

Next, we examine the specifics of Python’s mechanisms for passing arguments to and returning values from functions. These mechanisms are conceptually very simple, but it is worthwhile to take the time to understand them fully, as the effects are actually profound. Understanding argument-passing an...
