Answersdifferences between object-oriented programming and structural programming?
- hr@izetam.com February 10, 2022 in United States
Object-oriented Programming
Follows a bottom-up approach.It provides data hiding.
It is used to solve complex problems.
It allows reusability of code that reduces redundancy of code.
It is based on objects rather than functions and procedures .
It provides more security as it has a data hiding feature.
It focuses on data .
More abstraction more flexibility.
Structural Programming
Follows a top-down approach.
. Data hiding is not allowed.
It is used to solve moderate problems.
Reusability of code is not allowed.
. It provides a logical structure to a program in which the program is divided into functions.
It provides less security as it does not support the data hiding feature.
More abstraction more flexibility.
