  §   The pictorial representation of an algorithm with specific symbols for instructions & arrows showing the sequence of operations is known as “FLOWCART”. §   The basic geometric shapes to denote different types of instructions. And these boxes are connected by solid lines with arrow mark to indicate the flow of operations. §   An algorithm is converted into a flowchart   & then instructions are expressed in some programming language. §   The main advantage of this two-step approach . That is ,while drawing a flowchart one is not concerned with the details of the elements of programming language. §   Since a flowchart show of operations in pictorial form, any error in the logic of the procedure can be detected more easily than in a program.   FLOWCHART SYMBOLS 1. Terminal §   It is used to indicate the beginning (START) & ending (STOP) in the program logic flow. §   It has the shape of an ellipse 2. Input/Output §   The parallelogram is used as t
