Question:
For the code snippet shown below, which of the following statements are valid?

public class Generic<T>
{
    public T Field; 
    public void TestSub()
    {
        T i = Field + 1;
    }
}
class MyProgram
{
    static void Main(string[] args)
    {
        Generic<int> gen = new Generic<int>();
        gen.TestSub();
    }
}

1.Addition will produce result 1.

2.Result of addition is system-dependent.

3.Program will generate run-time exception.

4.Compiler will report an error: Operator '+' is not defined for types T and int.
