each of the smaller problems.

Answer 1

Procedural Programming

Question 2

This model of software development is process-centric or procedural since it concentrates on
the procedures in a system.

Answer 2

Procedural Programming

Question 3

It describes the task to be performed on objects. These objects that have to be created
and stored in the computer memory, contain data and instructions to perform tasks specific to
that object.

Answer 3

collection of variables, data structures, and subroutines

Answer 4

procedural programming

Question 5

objects that expose behavior (methods) and data (members or attributes) using
interfaces.

Answer 5
