Decomp and Abstra

Question 1

ALGORITHMS -

Answer 1

a set of instructions for solving a problem or completing a task.

Question 2

ABSTRACTION

Answer 2

involves removing unnecessary detail from a problem so that you can focus on the essential components to add to a solution

Question 3

Decomposition –

Answer 3

involves breaking down a large problem into smaller subproblems so they are manageable
Then the sub-problems can be broken down further until each small task is manageable

Question 4

Advantages of Decomposition :

Answer 4

The problem becomes easier to solve when it consists of a number of small subtasks
or subprograms
Some subprograms may be reusable in other programs, saving development time
Smaller problems can be tested independently so easier to identify a problem.

Question 5

Why are subprograms so useful

Answer 5

Reusability: Once written, a subprogram can be used multiple times in different parts of a program.
Modularity: It helps break a large program into smaller, more manageable chunks.
Readability and Maintainability: Smaller, focused subprograms make the code easier to read, understand, and debug.
