1. FLOWCHART NIDA CHAUDHARY

2. DEFINITION A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution model to a given problem. The process of drawing a flowchart for an algorithm is known as “flowcharting”.  Nida Chaudhary

3. ADVANTAGES OF FLOWCHART Flowcharts are better way of communicating the logic of system. Flowcharts act as a guide for blueprint during program designed. Flowcharts helps in debugging process. With the help of flowcharts programs can be easily analyzed. It provides better documentation. Flowcharts serve as a good proper documentation. Nida Chaudhary

4. DISADVANTAGES OF FLOWCHART It is difficult to draw flowchart for large and complex programs. In this there is no standard to determine the amount of detail. Difficult to reproduce the flowcharts. It is very difficult to modify the Flowchart. Nida Chaudhary

5. BASIC SYMBOLS Terminal:   The oval symbol indicates Start and Stop the flowchart. Input/Output:   A parallelogram denotes any function of input/output type. Nida Chaudhary Start Stop Input Output

6. BASIC SYMBOLS Processing:   A box represents arithmetic instructions. Decision:   Diamond symbol represents a decision point. Nida Chaudhary Processing Decision

7. BASIC SYMBOLS Connectors:   Whenever flowchart becomes complex or it spreads over more than one page. Flow lines:   Flow lines indicate the exact sequence in which instructions are executed.  Nida Chaudhary Circle
