Imperative programming reflects the sequential nature of computer operations and uses sequences, selections, and iterations of commands. Object-oriented programming was developed to improve efficiency and reduce errors in complex software. Concurrent programming was developed for programs using multi-processor systems to make efficient use of resources. Imperative programming, also called procedural programming, consists of executable commands combined into modular blocks of self-contained code.

2. Imperative Programming - Reflects the sequential
nature of the operation of the computer
Object Oriented Programming - Developed to
improve programmer efficiency and to reduce errors
in complex software
Concurrent Programming - Developed from
programs written to make efficient use of multi
processor systems

3.  Imperative Programming – A program consists of a set of executable
commands, how these commands are executed will depend on how the three
basic control structures have been used:
 Sequence - one command is executed followed by another
 Selection - if a condition is true then one command is executed, else if that
condition is false then a different command is executed
 Iteration - a command is executed a set number of times

4.  Imperative Programming is sometimes referred to as Procedural Programming.
 Being able to combine commands into a single block of self-contained code is referred
to as Modularity.
