Answer:
A. When declaring a variable, you also specify the type of its values.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
For instance, to pass a class to a family of classes use the code;
\\parameter Name as Type (Keywords) = value;
\\procedure XorSwap (var a,b :integer) = "myvalue";
<em>Hence, the true and correct statement is that when declaring a variable, you also specify the type of its values such as integers, string, etc. </em>
