6. 6. What is algorithm? • An algorithm is a representation of a solution to a problem. • An algorithm is procedure consisting of a finite set of unambiguous rules (instructions) which specify a finite sequence of operations that provides the solution to a problem, or to a specific class of problems for any allowable set of input quantities (if there are inputs). In other word, an algorithm is a step-by-step procedure to solve a given problem
7. 7. What is algorithm flowcharts? • A flowchart is a diagram made up of boxes, diamonds and other shapes, connected by arrows - each shape represents a step in the process, and the arrows show the order in which they occur. Flowcharting combines symbols and flowlines, to show figuratively the operation of an algorithm. • A flowchart is a type of diagram that represents an algorithm or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. • Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields
8. 8. Properties of an Algorithm • Finiteness: - an algorithm terminates after a finite numbers of steps. • Definiteness: - each step in algorithm is unambiguous. This means that the action specified by the step cannot be interpreted (explain the meaning of) in multiple ways & can be performed without any confusion. • Input:- an algorithm accepts zero or more inputs • Output:- it produces at least one output. • Effectiveness:- it consists of basic instructions that are realizable. This means that the instructions can be performed by using the given inputs in a finite amount of time.
9. 9. Symbols of flowcharts • Start and end symbols • Arrows • Generic processing steps • Subroutines • Input/Output • Prepare conditional • Conditional or decision • Junction symbol • Concurrency symbol • Labeled connectors

11. 11. Types of flowchart • Document flowcharts, showing controls over a document-flow through a system • Data flowcharts, showing controls over a data- flow in a system • System flowcharts showing controls at a physical or resource level • Program flowchart, showing the controls in a program within a system
12. 12. Advantages of Flowchart • It provides an easy way of communication because any other person besides the programmer can understand the way they are represented. • It represents the data flow. • It checks the accuracy in logic flow. • It documents the steps followed in an algorithm. • It provides the facility for coding. • They shows all major elements and their relationship. • It provides the way of modification of running program.
13. 13. Limitation of Flow Charts • It is the total perception of the designer who draw the flowchart. • It's working differ from one compiler to another ,one language to another in some time. • It need weldefined requiremnts. • Its basically for structured programming.
