Flowchart In C Language
Flowchart is a graphical representation of an algorithm.
Programmers often use it as a program-planning tool to solve a problem.
It
makes use of symbols which are connected among them to indicate the flow of
information and processing.
The process of drawing a flowchart for an algorithm is known as “flowcharting”.
Basic Symbols used in Flowchart Designs
1.Terminal: The oval symbol indicates Start, Stop and Halt in a program’s logic flow. A pause/halt is generally used in a program logic under some error conditions. Terminal is the first and last symbols in the flowchart.

2.Input/Output: A parallelogram denotes any function of input/output type. Program instructions that take input from input devices and display output on output devices are indicated with parallelogram in a flowchart.

3.Processing: A box represents arithmetic instructions. All arithmetic processes such as adding, subtracting, multiplication and division are indicated by action or process symbol.

4.Decision: Diamond symbol represents a decision point. Decision based operations such as yes/no question or true/false are indicated by diamond in flowchart.

5.Connectors: Whenever flowchart becomes complex or it spreads over more than one page, it is useful to use connectors to avoid any confusions. It is represented by a circle.

6. Flow lines: Flow lines indicate the exact sequence in which instructions are executed. Arrows represent the direction of flow of control and relationship among different symbols of flowchart.
Example :
Draw a flowchart to input two numbers from user and display the largest of two numbers
