When variables are declared in the body of a method they are know as what?
Local Variables There are two types of variables based on the location of declaration 1. Instance Variables- Declared inside a class, but outside of any method's body. 2. Local Variables- Declared inside a method's body inside a class.
In java all variables declared using a class are?
Reference variables
What is meant by delare or initialize a variable or constant at a lowest possible level?
It probably refers to "scope" (see http://en.wikipedia.org/wiki/Scope_(programming)). In programming languages with lexical scope, variables declared in an outer scope can be used in an inner scope, but variables declared in an inner scope cannot be used in outer scopes. It is considered best practice to declare variables (and constants, which are just variables that don't change) at the innermost scope possible for several reasons: # It makes it most clear what the scope of use is of the variable. # It makes it impossible to mistakenly use it in some other location. # It makes it easier to keep track of what variables exist at any given point in the code. For example, in standard C, nested functions are not allowed. This means that in any function, only two types of variables exist - global variables, and variables declared within that function. This has the advantage of making it easy to understand what any variable refers to.
What are the element of the visual basic?
A declared element is a programming element that is defined in a declaration statement. Declared elementsinclude variables, constants, enumerations, classes, structures, interfaces, procedures, procedure parameters, function returns, external procedure references, operators, properties, events, and delegates
How are constants and variables important in devoloping java programs?
Without variables, you won't be able to do much programming. Variables is where you store data; such data may change over time. And computer programming is all about manipulating data.
Can static variables be declared in a header file in C programming?
Yes (but usually it is a bad idea).
What are variables in programming?
In computer programming, variables refer to a particular location in the memory that holds a value. Variables are equivalent to their assigned values.
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 type of linear programming can be found by graphical methods?
A linear programming question with two variables. Problems with three can be solved if there is a constraint that reduces them to effectively two variables. Linear programming with 3 variables, using 3-d graphs is possible but not recommended.
What is the scope of register variables?
The block they are declared in.

What are variables in 3 words?
Variables are placeholders for values. They can change or vary. In programming, they store data.
Can you explain the difference between pointers and variables in programming languages?
In programming languages, variables are used to store data values, while pointers are variables that store memory addresses of other variables. Variables directly hold data, while pointers hold the location of where data is stored in memory.
