The inventor of the numeral-type for China, by the use of which illiterate Chinese both blind and sighted can very quickly be taught to read and write fluently

If the type is a struct, it will return each member of the struct initialized to 0 (for numeric types) or null (for reference types). Advantages of Generics It's not difficult to see the advantages of using generics: ? Type safety — Generic types enforce type compliance at compile time, not at runtime (as in the case of using Object). This reduces the chances of data-type conflict during runtime. ? Performance — The data types to be used in a generic class are determined at compile time, so there's no need to perform type casting during runtime, which is a computationally costly process. ? Code reuse — Because you need to write the class only once and then customize it for use with the various data types, there is a substantial amount of code reuse. Using Constraints in a Generic Type Using the MyStack class, suppose that you want to add a method called Find() that allows users to check if the stack contains a specific item. You implement the Find() method like this: public class MyStack<T> {  private T[] _elements;  private int _pointer;  public MyStack(int size) {   _elements = new T[size];   _pointer = 0;  }  public void Push(T item) {   if (_pointer > _elements.Length - 1) {    throw new Exception("Stack is full.");   }   _elements[_pointer] = item;   _pointer++;  }  public T Pop() {   _pointer--;   if (_pointer < 0) {    return default(T);    //throw new Exception("Stack is empty.");   }   return _elements[_pointer];  }  public bool Find(T keyword) {   bool found = false;   for (int i=0; i<_pointer; i++) {    if (_elements[i] == keyword) {     found = true;     break;    }   }   return found;  } } But the code will not compile ...»
