For the code snippet shown below, which of the following statements are valid? public class TestCuriousTab { public void TestSub (M arg) { Console.Write(arg); } } class MyProgram { static void Main(string[] args) { TestCuriousTab tab = new TestCuriousTab(); tab.TestSub("CuriousTab "); tab.TestSub(4.2f); } }

Program will compile and on execution will print: CuriousTab 4.2
A non generic class Hello cannot have generic subroutine.
Compiler will generate an error.
Program will generate a run-time exception.
None of the above.

Correct Answer: Program will compile and on execution will print: CuriousTab 4.2

For the code snippet given below, which of the following statements is valid? public class Generic { public T Field; } class Program { static void Main(string[ ] args) { Generic g = new Generic(); g.Field = "Hello"; Console.WriteLine(g.Field); } }
For the code snippet given below, which of the following statements are valid? public class MyContainer where T: IComparabte { // Insert code here } Class MyContainer requires that it's type argument must implement IComparabte interface. Type argument of class MyContainer must be IComparabte. Compiler will report an error for this block of code. This requirement on type argument is called as constraint.
For the code snippet given below, which of the following statements are valid? public class MyContainer where T: class, IComparable { //Insert code here } Class MyContainer requires that it's type argument must implement IComparable interface. Compiler will report an error for this block of code. There are multiple constraints on type argument to MyContainer class. Class MyContainer requires that its type argument must be a reference type and it must implement IComparable interface.
