2. Flowcharst and Algorithms to Solve Problems

Flowchart

A flowchart is a graphical representation of an algorithm. There are name and symbols are use to draw flowchart.

Flowcharts for Sequential, Decision-Based and Iterative Processing.

Sequential Processing

The sequential (Sequence) construct means the statements are being executed sequentially. This is the default flow of statements.

Decision-Based Processing

Conditional / Selection logic, also known as decision logic, is used for making decision. It is used for selecting the appropriate path out of two or more alternative paths in the program logic.

Iterative (Looping) Processing

Many jobs that are required to be done with the help of a computer are repetitive of nature. To solve this type of problem we are used iterative processing.

Terms used in Looping

Initialization

It is the preparation required before entering a loop.

Incrementation

It is the process where numerical value is added or subtracts to the variables each time on goes round the loop.

Loop Exit Condition

It is the conditional that use to iterative processing.

True - Numbers of times loop running.

False - That time exit from the loop.

How to write a general flowchart ?

Writing a general flowchart involves a systematic representation of a process or algorithm using various symbols and connecting arrows. Here's a step-by-step guide on how to create a basic flowchart
