What is a Flowchart? Explain use of different symbols in drawing of Flowchart with the help of an example.

A flowchart is a visual representation of the steps in a process, showing the sequence of actions using symbols. It helps in understanding, analyzing, and designing processes.

Common symbols include:

1. Oval: Start/End of the process.
2. Rectangle: A process or operation.
3. Diamond: Decision point, branching based on a condition.
4. Parallelogram: Input/Output operations.
5. Arrow: Flow direction from one step to another.

Example: Flowchart for making a cup of tea.

1. Start (Oval): Begin the process.
2. Boil Water (Rectangle): Heat water.
3. Add Tea Leaves (Rectangle): Put tea leaves into the teapot.
4. Water Boiled? (Diamond): Check if water is boiling.
   • Yes: Proceed to the next step.
   • No: Go back to boiling water.
5. Pour Water (Rectangle): Pour boiling water into the teapot.
6. Steep Tea (Rectangle): Let tea steep for a few minutes.
7. Pour Tea (Parallelogram): Serve tea in a cup.
8. End (Oval): Process complete.

This flowchart illustrates the sequential steps and decision-making involved in making tea.
