Why use flowcharts ?

Normally, an algorithm is first represented in the form of a flowchart, and a flowchart is then expressed in some programming language to prepare a computer program. The main advantage of this two-step approach in program writing is that, while drawing flowchart , a programmer is not concerned with the details of the elements of programming language. Hence he/she can fully concentrate on the logic of the procedure. Moreover, since a flowchart shows the flow of operation in pictorial form, any error in the logic of the procedure can be detected more easily than in the case of a program. Once the flowchart is ready, the programmer can forget about the logic, and can concentrate only on coding the operation in each box of the flowchart in terms of the statements of the programming language. This will normally ensure an error-free program.
