The equal sign is used to assign values to the variable. The most natural size of integer for the machine. Constructors: a)initialize instance variables b)when overloaded, can have identical argument lists c)when overloaded, are selected by number and types of parameters d)a and c. d)a and c. The data components of a class are called instance variables. Two type arguments are provably distinct if one of the following is true: Neither argument is a type variable or wildcard, and the two arguments are not the same type. True/False. (function() { Here is the general syntax: Dim variableName As DataType. !boolean isTurnedOn = true;! We can calculate the mean, median, mode, standard deviation, and a variety of other descriptive statistics for these variables. That type is called a Boolean type (note: Boolean is properly capitalized in the English language because it’s named after its inventor, George Boole). The default initial value of a boolean variable data type. 13. To review, a variable may be declared and initialized using the following syntax: [variable type] [variable name]( = [current value]); The initizializing, in (), is optional, but it is good practice to do so to avoid unexpected behavior.
