What is a flowchart? How many types of flowcharts and what are they? describe
The method in which the program is expressed with the help of diagrams or symbols is called a flowchart.
Example: Write the algorithm and flowchart to find the sum of three numbers.
Types of Flowcharts:
- Flowcharts are basically of 2 types.
1. System Flowchart:
The flow chart that shows the data flow, processing, storage, and display of results of a system is called a system flowchart.
Symbols of System Flowcharts.
2. Program Flowchart:
The flowchart that is created in the program writing is called program flowchart.
Symbols of Program Flowcharts.
Symbols of Program Flowcharts and Their Usage:
1. Terminal symbol: It is oval-shaped. It is used to start or end the program on a flowchart every time.
2. Intake or emission symbol: It is parallel-shaped. It is used for input and output in the program.
3. Processing symbol: It is rectangular in shape. It is used for processing. For example, mathematical calculations.
4. Decision symbol: It is diamond-shaped. It is used for decision-making. By using output yes or no.
5. Straight lines with arrows Symbol: It indicates the direction of program flow.
6. Connection symbol: when a large flowchart does not fit on one page, then use it to connect and draw the rest on the other page.
The rules for drawing flowcharts:
1. Flowcharts should be drawn using certain symbols.
2. The flowchart should be made with arrow symbols and the flow should not be from bottom to top or from right to left.
3. The text inside each symbol must be legible.
4. The use of extra symbols should be avoided.
5. No specific programming language should be used.

Algorithm Vs Flow Chart:
The Key Difference between Algorithm And Flowchart.
Algorithm:
In this case, each problem is solved step by step, so it is known as an algorithm.
It is description-based.
In the case of algorithms, it takes a lot of time to understand the program.
The direction of the program flow is not easy to understand.
It is difficult to eliminate program errors.
Flowchart:
The steps of solving a problem are expressed in a diagram using various symbols.
It is image-based.
It takes less time to understand the program.
The direction of the program flow is easy to understand.
It is easy to eliminate program errors.
What is pseudocode?
- Pseudo is a Greek word. The word sudo means fake or artificial. It may look like programming code, but it is not.
Programmers often create a draft text version of the code that is written for the program, and that is called pseudocode.
