Answer the following statements true (T) or false (F)

Question

1) A single array can store values of many different types.
2) An array index should normally be of type float.
3) An individual array element that’s passed to a method and modified in that method will contain the modified value when the called method completes execution.
4) Command-line arguments are separated by commas.
5) Auto-implemented properties cannot be initialized in their declarations.

Answer 1

1) False. An array can store only values of the same type.
2) False. An array index must be an integer or an integer expression.
3) For individual value-type elements of an array: False. A called method receives and
manipulates a copy of the value of such an element, so modifications do not affect
the original value. If the reference of an array is passed to a method, however, modifications to the array elements made in the called method are indeed reflected in the original. For individual elements of a reference type: True. A called method receives a copy of the reference of such an element, and changes to the referenced object will be reflected in the original array element.
4) False. Command-line arguments are separated by whitespace.
5) False. As of C# 6, you can use auto-property initialization in auto-implemented
property declarations.
