The dependent variable.
The dependent variable is the variable that depends on the independent variable.
the test variable is the independent variable.

Declaration is a promise: 'I will define (or has defined) this variable/function somewhere else'.
I'll give you an example: char *s;
type variable {[optional array size]} {= optional initializer};
When declaring a variable, don't use short and cryptic names such as 'x'. Use descriptive names for the variable, such as 'accumulator'. Also, don't declare more than one variable on the same line. You can, but it will help take some errors away from your code.
No, unless you do not use it at all.
Variable declaration is when you declare a variable. For example: String foo; The data type is String and now I can modify foo and don't need to type String again. It can be an instance variable or a local variable.
Forward reference is a terminology of coding standards. It is in which a variable is used before declaring it.
You can unset a variable in PHP by setting it to NULL. You can set a variable to NULL by declaring it normally, or using the function "unset()". Both methods are acceptable, and accomplish the same thing. Examples of both: ---- $variable = NULL; ---- unset($variable); ----

displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
In languages like C, declaring a variable "volatile" tells the compiler that it can't assume that the variable is only changed by the program code. If the variable is not declared volatile, sometimes the compiler can make certain optimizations since it can assume that it knows everything about how the variable will be used. When it is declared volatile, the variable may be changed by an external process (for example, it could be connected to an I/O device), so it must always be fetched from memory.
