FLOWCHARTS IN PROGRAMMING

WHAT ARE FLOWCHARTS ?

Flowcharts are graphical means of representing the logic to solve any computational problem.

It is a pictorial way and hence give more intense understanding of the solution for the problem at hand.It consist of some symbols which forms its tools to make a complete structure for any problem.

These symbols are :
