Print Details Category: Chapter 3 Published: Sunday, 14 April 2013 16:20 Written by Sternas Stefanos Hits: 12969 The call by reference method of passing arguments to a subprogram copies the address of an argument into the formal parameter. Inside the subprogram, the address is used to access the actual argument used in the call. Pass-by-reference means to pass the reference of an argument in the calling function to the corresponding formal parameter of the called function.

Well, in reality, neither of those is a great reason to pass by pointer. In fact, they are both great reasons to pass by reference. In the first case, you'd pass by non-const reference.

By removing the ability to include the reference sign on function calls where pass-by-reference is incurred (I.e., function definition uses &), the readability of the code suffers, as one has to look at the function definition to know if the variable being passed is by-ref or not (I.e., potential to be modified).

Passing parameters by value is the default: the value is copied on the stack and the routine uses and manipulates the copy, not the original value. Pascal also has true pass-by-reference parameters. The most common use for pointers is interfacing to C and C++ code, including the Windows API. C and C++ programmers will be glad that Delphi's rules for using pointers are more C-like than Pascal-like. Irie Pascal supports passing arrays, so in this case you should pass an array by reference to the C function or procedure.

In essence, you can pass in the symbolic "name"; of a variable, which allows it both to be accessed and updated. 2021-03-27 · In the paragraph "Pass by const reference", right after the sentence "Using const is useful for several reasons:", points 3 and 4 overlap.
