variable definition means to declare the variable with its value. for example:- int i=10; this statement is a combination of declaration of integer i and assign its value to it,so it is a definition statement Note: assigning a value is not essential.
Operational definition. :)
A declaration and definition of a variable are nearly synonymous, especially as it is found in source code. However, the concepts are separate. The definition of a variable may include variable name, type, scope, operating range, and initial value(s). Program documentation includes only the definition of a variable; not the declaration. It defines the meaning and use of a variable. Whereas the declaration of a variable indicates to the compiler/interpreter that the name should be recognized as a variable. Understand that when the variable declaration is given in source code it may include the definition, though not always. In some languages a variable may be declared and then defined later as to type, operating range, et al.
