Question 1: Why are generics used?
Generics make code more fast
Generics make code more optimised and readable
Generics add stability to your code by making more of your bugs detectable at compile time
Generics add stability to your code by making more of your bugs detectable at run time
Question 3: Which of these is an correct way of defining generic method?
name(T1, T2, …, Tn) { /* … */ }
public name { /* … */ }
class name[T1, T2, …, Tn] { /* … */ }
name{T1, T2, …, Tn} { /* … */ }
Question 4: What will be the output of the following C# code snippet?
public class Generic<T> { Stack<T> stk = new Stack<T>(); public void push(T obj) { stk.Push(obj); } public T pop() { T obj = stk.Pop(); return obj; } } class Program { static void Main(string[] args) { Generic<int> g = new Generic<int>(); g.push("Csharp"); Console.WriteLine(g.pop()); Console.ReadLine(); } }
