Pass by reference Even though C always uses 'pass by value', it is possible simulate passing by reference by using dereferenced pointers as arguments in the function definition, and passing in the 'address of' operator & on the variables when calling the function.

It requires less typing to declare variables, especially when declaring a variable as a nested generic type. It must be used when storing a reference to an object of an anonymous type, because the type name cannot be known in advance: var foo = new { Bar = "bar" }; You cannot use var as the type of anything but locals. To pass a value by reference, argument pointers are passed to the functions just like any other value. So accordingly you need to declare the function parameters as pointer types as in the following function swap() , which exchanges the values of the two integer variables pointed to, by their arguments.
