Q1: Explain the concept of flowchart and algorithm development in C.
Answer : Flowcharts in C
A flowchart is the diagrammatic representation of an algorithm. It is very helpful in writing programs and explaining the logic of a program to others.
Symbols Used in Flowcharts
1. Arrow (→)
Used to indicate the flow of logic by connecting different symbols.
2. Terminal (Start/Stop)
Represented by an oval shape.
Used to represent the start and end points of a flowchart.
3. Input/Output
Represented by a parallelogram.
Used for input and output operations.
4. Processing
Represented by a rectangle.
Used for arithmetic operations and data manipulations.
5. Decision
Represented by a diamond shape.
Used for making decisions within the flowchart.
6. On-Page Connector
Represented by a small circle.
Used to join different flow lines on the same page.
7. Off-Page Connector
Represented by a pentagon shape (home plate).
Used to connect flowchart segments across different pages.
8. Predefined Process / Function
Represented by a rectangle with double vertical lines on both ends.
Used to represent a group of statements that perform a single processing task.
