Question

Look at the following code:
int n = '3' + '4';
char c = (char)n;
System.Console.WriteLine(c); 

If we run it, what would be the result?

    • 7

    • None of the mentioned.

Question

You have following line:

FileStream fs = new FileStream("myFile.txt", FileMode.Open);
try {
    // ... Write to the file ...
}
finally {
    if (fs != null)((IDisposable) fs).Dispose();
}

What is the purpose of finally block?

Answer
    • The finally block ensures that the Dispose method is called when the garbage collector is not working.

    • The finally block ensures that the Dispose method is called only if an exception is thrown.

    • The finally block ensures that the Dispose method is called even when an exception is thrown or the code exits the block early.

    • None of the mentioned
