Flowchart | Flowchart symbols with examples | Flowchart structure | advantages of flowchart | CBSE
In this Python tutorial for beginners, we will learn flowcharts. This Python tutorial video covers: what is a flowchart?, flowchart symbols, flowchart structures, flowchart examples, and the advantages of flowcharts. We have discussed the sequence, selection, and repetition forms of flowcharts with examples.
What is a flowchart ?
A flowchart is a tool to show the logic flow of a program. A flowchart gives a pictorial representation of an algorithm.The primary purpose of a flowchart is to show the design of an algorithm.
A flowchart uses special shapes to represent different types of actions or steps in a process.
We will discuss some standard symbols, which are frequently required for flowcharts.
Flowchart structures:
There are mainly three key constructs which are used in drawing a flowchart.
1. Sequence
2. Selection
3. Repetition
1. Sequence :
In a sequence structure, the instructions to be computed simply follow one another in a logical progression.
2. Selection:
A selection structure allows the program to make a choice between two alternative paths depending upon the condition, that is, whether it is true or false.
3. Repetition or loop:
When a sequence of statements is repeated against a condition, it is said to be in a loop.
Using looping, the programmer avoids repeating the same set of instructions.
The looping process can be either one time or multiple times until the desired output is obtained within a single program.
Advantages of flowchart:
1. Makes the logic easier to understand
2. Easier to communicate
3. Coding is easy
4. Program Documentation
This video will help you learn flowchart techniques without any prior programming language knowledge.
After watching this flowchart tutorial video, you will easily be able to answer questions about flowchart in Python and you write codes without making any mistakes.
