what are the computer programming variables?

Variables are data values that can change when the user is asked a question, for example, their age. Variables may change during program execution. A variable is a memory location . It has a name that is associated with that location.

Variable is a named storage of some data type(like int, float etc). And Objects are variables of data types that are user defined. So we say that an object is an instance of a class. And class is nothing but a user defined data type.

The value of a variable or a constant is any number or other mathematical object assigned to it. The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values.

There are two types of variables: global variables and local variables. The scope of global variables is the entire program whereas the scope of local variable is limited to the function where it is defined.

The Three Types of Variables There are three basic levels of scope in Java: local, instance and static.

Instance Variables. Instance Variables are added to object types but store numbers, text or booleans (on/off flags) individually for each instance. ... For example, a Boolean instance variable could be used to determine if an enemy is hunting down the player (true) or running away (false).

A variable is basically the name of the location in the primary memory of your computer. This can be chosen by you. A variable can store everything from strings to numbers. A string is the values inside the quotes assigned to a string.

Var is used to declare Implicitly typed variable where the compiler identifies the type automatically. var can hold any type of data. String is an explicit declaration for holding string data only. ... 'var' is used for declaring implicit types be it an int , string , double , an object etc etc.

There are three kinds of Java variables: Local variables are declared in a method, constructor, or block. ... Local variables are not visible outside the method. Instance variables are declared in a class, but outside a method. They are also called member or field variables.

The variables are declared using var keyword are statically typed. The variables are declared using dynamic keyword are dynamically typed. The type of the variable is decided by the compiler at compile time. The type of the variable is decided by the compiler at run time.

In other words, a variable in a python program gives data to the computer for processing. Every value in Python has a datatype. Different data types in Python are Numbers, List, Tuple, Strings, Dictionary, etc. Variables can be declared by any name or even alphabets like a, aa, abc, etc.

Constant in Java A constant variable is the one whose value is fixed and only one copy of it exists in the program. Once you declare a constant variable and assign value to it, you cannot change its value again throughout the program. ... once you declare a variable final you cannot modify its value again.

A variable is a named memory location which temporarily stores data that can change while the program is running. A constant is a named memory location which temporarily stores data that remains the same throughout the execution of the program. The type of a variable indicates what kind of value it will store.
