How to use flow chart in programming?

Question

C

Answer 1

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”.
The advantages of program flowchart are as follows:

Program flowchart can help programmers to find the bug in the process before carrying out.
It works as a blueprint when analyzing the systems and developing programs, which makes coding more efficient.
It improves programmers’ efficiency in maintaining the operating program.
With the help of program flowchart, communicating the logic of a system to all concerned gets much easier.

Answer 2

To add to what Thirteen said, its a visual representation of some pseudo code.

Take your finger and start at wherever it starts and "act" as if you are the computer making descisions. At each fork that you make a descision at, just follow whatever path you choose and make the next decision.
