6. What would be the value of x and y after executing this code?
Dim x as Integer
Dim y as String
x = 3
y = “my_test”
x = x + y.Length
y = y & “_again”
x is 10, because x was 3 and the length of y is 7 so 3 + 7 = 10
y is the string “my_test_again”, y was the string “my_test” then it was set to
y concatenated with “_again”, making the string “my_test_again”
