C# (Sharp) Programming Language

Answer1

It would work fine. As the runtime type of 123.34 would be double, and Double can be converted to Integer.

Answer2

the ctype(123.34,integer) will work fine no errors

It would throw an InvalidCast exception as the runtime type of 123.34 (double) doesnt match with Integer.

Answer1

A Sub does not return anything whereas a Function returns something.

Answer2

-A Sub Procedure is a method will not return a value

-A sub procedure will be defined with a “Sub” keyword

Sub ShowName(ByVal myName As String)

Console.WriteLine(”My name is: ” & myName)

End Sub

-A function is a method that will return value(s).

-A function will be defined with a “Function” keyword

Function FindSum(ByVal num1 As Integer, ByVal num2 As Integer) As Integer

Dim sum As Integer = num1 + num2

Return sum

End Function

You must use the Missing class and pass Missing.Value (in System.Reflection) for any values that have optional parameters.

There are imperative and interrogative functions. Imperative functions are the one which return a value while the interrogative functions do not return a value.
