What is the difference between a constant and a variable in java programming language?
A constant in Java is defined using the "final" modifier. For instance:
final double Density_Of_Water = 1.000;
would set Density_Of_Water to 1.000. This value can not be modified throughout the program because "final" told the compiler that this value would not change. A variable however, can be changed by the user throughout the program.

What is a constant as used in C programming?
A variable of which the value cannot change. Example of its usage: const int foo = 5;
Why use static variable in programming language?
For C programming, the use of a static variable has two uses: One reason is to hide the variable from other modules. The scope of the static variable is limited to the compilation unit that it is described in. The second use of a static variable is to keep the value of the variable intact through the entire program execution unit.
Is “C language” case sensitive programminIs “C language” case sensitive programming language If yes why and if no whyg language If yes why and if no why?
C is case sensitive, which means that, for example, $var and $VAR are not the same variable.
Translating an algorithm into a programming language is called?
Translating an algorithm into a programming language is called coding. A variable declaration tells the operating system to allocate storage space in RAM.
What is the difference between a variable and a literal in prgramming?
a literal is a constant value, the difference is a variable can change it's value.

What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is a computer variables?
In a programming language, a variable is a name for a place where information is stored.
When do you declare a variable?
You declare a variable when you create it by specifying its datatype and name in a programming language. This tells the compiler or interpreter to allocate memory for the variable. Variables must be declared before they can be used in most programming languages.
What is difference between variable and constant?
Whether or not you can change its value.
What is a constant variables in c language?
It are a variable you add modifer 'const' to. It means these variable mustn't be modified.
What are the differences of a constant and a variable?
A constant has only the exact value it's declared and can never be changed. A variable can have any number of values assigned. In programming, a variable can be given a value later in the code but can only be changed during runtime if its been declared as a pointer.
Difference between variable and constant in statistics?
When referring to statistics, variable means that numbers change and can go up and down. If something is constant, numbers remain unchanged.
What is a variable that you need to keep the same?
A constant is a variable that needs to remain the same throughout a specific process or calculation in programming. It does not change its value once it has been defined.
What is a constant as used in C programming?
A variable of which the value cannot change. Example of its usage: const int foo = 5;
How do you delete reference of an object?
This often happens automatically, when the variable that references an object goes out of scope. Alternatively, you can set the variable that refers to an object to some reserved value, such as NULL (details vary, depending on the programming language).This often happens automatically, when the variable that references an object goes out of scope.
