Q: What is the VAR keyword used for in X++?  

Answer: B

Justification:

1. A variable cannot change data type without explicitly changing or converting the data type with a code statement.
2. The VAR keyword allows a variable to be defined without explicitly specifying the type; the compiler will automatically determine the data type based on the mandatory initialization expression.
3. An array can be declared using a data type. For example, “int myArray[10]”, declares an array of type integer with up to 10 values.
4. A container is declared using the container keyword. For example, “container myContainer”. A container can store variables of mixed data types.
