Initialization is distinct from (and preceded by) declaration, although the two can sometimes be conflated in practice. The complement of initialization is finalization, which is primarily used for objects, but not variables. Initialization is done either by statically embedding the value at compile time, or else by assignment at run time.
An assignment operation is a process in imperative programming in which different values are associated with a particular variable name as time passes. [1] The program, in such model, operates by changing its state using successive assignment statements. [2] [3] Primitives of imperative programming languages rely on assignment to do iteration. [4]
In computer programming, a declaration is a language construct specifying identifier properties: it declares a word's (identifier's) meaning. [1] Declarations are most commonly used for functions , variables , constants , and classes , but can also be used for other entities such as enumerations and type definitions. [ 1 ]

In class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object.It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.
Resource acquisition is initialization (RAII) [1] is a programming idiom [2] used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant , and is tied to object lifetime .
The function register_student leaks memory contents because it fails to fully initialize the members of struct student new_student. If we take a closer look, in the beginning, age, semester and student_number are initialized. But the initialization of the first_name and last_name members are incorrect.
The declaration syntax for a pointer is DECLARE xxx POINTER;, which declares a pointer named "xxx". Pointers are used with BASED variables. A based variable can be declared with a default locator ( DECLARE xxx BASED(ppp); or without ( DECLARE xxx BASED; ), where xxx is a based variable, which may be an element variable, a structure, or an array ...
