Passing array to a function [pass by reference]

Question

I have declared an array y[21] in main and want to pass it to a function using pass by reference

Plz tell me whats wrong in following statements..

int y[21]; //array declaration

void printfunction(int *y); //protoype

printfunction(y); //call

what changes are required?

There is no concept of * i.e pointer in C#. System.Array is the Reference type so when you pass the array and call the function it will not create another copy of it within the function like value type. It will point to the same location. Sam Hobbs given you the solution. Follow it. Thanks

What language? If you are using C# then you need to learn the language. For C# you do not need a protoype; you can do something similar if you have a base class that you need to be able to override methods in derived classes but that is similar to the way that C++ works and you can learn about C# for deatils of C#. C# arrays are very different from C arrays. static void printfunction(int[] y) { } static void Main(string[] args) { int[] y = new int[21]; printfunction(y); }
