Most programming languages require that you declare all of the variables that you intend to use in a program. A variable declaration is a statement that typically specifies two things about a variable:
* The variable's name
* The variable's data type

What part of a function definition specifies the data type of the value that the function returns?
The function header. The return value is written before the name of the function. This return type must match the type of the value returned in a return statement.
How do variables and symbollic names differ?
Variables are storage areas that hold data that can vary during the execution of a program. A symbolic name is the name given to any entity in a program, including variables, constants, functions, procedures and various other stuff.
In java difference between classes and object in tabluar form?
A class is a template to create objects. You define the general behavior of a new data type in a class; then you create objects as specific variables of the new type. In other words, you can consider the class as a data type.A class is a template to create objects.

What data or variable type is used for variables that will only have the values true or false?
Boolean
Why should you declare variables?
Declaring of a variable in Java refers to creating a variable of a particular data type. Example: int x = 10; Here we are declaring an integer variable X and initializing it to a value of 10
Specifies the kind of data a field can contain?
A field's data type specifies the kind of data it can contain, such as text, numbers, dates, or Boolean values. This helps ensure data integrity by restricting what type of data can be entered into that field, preventing errors and inconsistencies in the database. Choosing the appropriate data type for each field is important for accurately storing and organizing data.
What do you mean by data of types?
It specifies wat type of data is stored n memory occupied
What is datetypes?
datatype is a classification describing the type of the data. Eg:- Datatypes like float specifies the data to be floating point number, integer specifies the data to be a real number. It also specifies the possible values, default values, operations that can be carried on them.
What is the meaning of operand data type?
Operand data type is one of the two components of computer language and expressions. It is the manipulated object or the instruction that specifies which operation is to be performed.
What is categorical data?
Categorical data is the statistical data type consisting of categorical variables or of data that has been converted into that form, for example as grouped data.
