Flowcharts in C

Flowcharts in the C Language:


In the C programming language, a flowchart is used to visually represent the functionality of a program. A flowchart is a type of diagram that sequentially shows the steps and processes of a program using various symbols and arrows. It clearly depicts each stage of programming, making it easier to understand the program's flow.

What is a Flowchart?
A flowchart is a diagram that shows the steps of a process, system, or algorithm in sequential order. Its main purpose is to present the different stages of a process in a sequential manner so that the user can easily understand and follow it in the future.

Key Symbols of a Flowchart:
  • Oval/Ellipse (Terminator): Used for the Start or End point.
  • Rectangle (Process Box): Represents any operation or task within the program.
  • Diamond (Decision Box): Represents a decision (if-else) within the program.
  • Parallelogram (Input/Output Box): Shows where data is input into or output from the program.
  • Arrow (Flow Line): Connects different symbols and indicates the flow of the process.

The document provides examples of flowcharts for a simple C program that adds two numbers and another that checks if a number is positive, negative, or zero.

Advantages and Disadvantages of Flowcharts:
Advantages: Helps clarify program logic, aids in identifying errors, provides effective documentation, and simplifies complex problems.
Disadvantages: Can be complex for large systems, requires time and resources to create, and can be difficult to correct if an error is made.
