You did say pass by reference (const stack&) rather than pointer (const stack.) Branflakes91093. You need to dereference the pointer to get what it points to. General C Programming; Lounge; Jobs; Home. The call by reference method of passing arguments to a function copies the reference of an argument into the formal parameter. Inside the function, the reference is used to access the actual argument used in the call. This means that changes made to the parameter affect the passed argument. Passing parameters by references in C - We have discussed how we implement call by reference concept using pointers. Here is another example of call by reference which makes use of C reference −. Feb 27, 2010  When to pass parameters by value, by reference, and by pointer In college, students are taught that there are two times you should pass by pointer: 1.

C++ Pass By Reference Object

The call by reference method of passing arguments to a function copies the reference of an argument into the formal parameter. Inside the function, the reference is used to access the actual argument used in the call. This means that changes made to the parameter affect the passed argument.

To pass the value by reference, argument reference is passed to the functions just like any other value. So accordingly you need to declare the function parameters as reference types as in the following function swap(), which exchanges the values of the two integer variables pointed to by its arguments.

C++ Pass By Reference Array

For now, let us call the function swap() by passing values by reference as in the following example −
