6.6.1 Pointer versus Reference Parameters When specifying parameters for your functions you can choose between passing them as value parameters, pointers, or references. For example, bool GetColor(int r, int g, int b); // pass by value bool GetColor(int &r, int &g, int &b); // pass...
In this way, the value of the argument in the calling function can be modified by the called function. The following example shows how arguments are passed by reference. In C++, the reference parameters are initialized with the actual arguments when the function is called. In C, the pointer ...
Pass-by-referencemeans to pass the reference of an argument in the calling function to the corresponding formal parameter of the called function. The called function can modify the value of the argument by using its reference passed in. The following example shows how arguments are passed by ref...
You can modify your pass-by-reference C# example to illustrate this technique:C# using System; class Program { static void Main(string[] args) { int counter = 0; // Passing by reference. // The value of counter in Main is changed. Console.WriteLine(greet("Alice", ref counter)); ...

Example The following source code shows how an internal table that, for performance reasons, is implemented by reference is returned. For this reason, it cannot be declared as a RETURNING parameter. The tabular output parameter is explicitly initialized at the beginning of the method before new ...
array, thencoder.ref(arg)provides the address of the first element of the array. Thecoder.ref(arg)function does not contain information about the size of the array. If the C function must know the number of elements of your data, pass that information as a separate argument. For example:...
For example, in vorum repo, the post.v file has code as below: fn (app &App) inc_post_views(post_id int) bool { app.db.exec('update posts set nr_views=nr_views+1 where id=$post_id') return true //db := app.db //db.update Post set nr_views = nr_views + 1 where id ...
