The document discusses flow charts, which are graphical representations of problem-solving processes. Flow charts use different shapes to represent instruction types and should convey the main logic from left to right and top to bottom. They allow for effective problem-solving, coding, debugging, and testing but take more time to draw and can be difficult to change. The document provides examples of flow charts, including one to swap two numbers without a third variable and one to determine if a number is even or odd.

- 1. Presented by : SAPNA SHARMA
- 2. A flow chart is a graphical representation of the sequence of operation for the solution of a problem. Flow chart use boxes of different shapes to denote different types of instruction.
- 3. First think of the main line of logic , then incorporate details . Do not give every details on the flow chart. Statement in the flow chart symbols should be précis and easy to understand . Use discripted variable names .
- 4. Go from left to right and top to bottom while constructive flowchart If a new flow charting page is needed it is recommended that the flow chart be broken at an input or output point. Moreover properly labeled connectors should be used to link the portion of the flow chart on different pages.
- 5. Convey better meaning Effective joining of part of system. Efficient coding. Systematic debugging. Systematic testing.
- 6. Take more time to draw. Difficult to make change. Non standardization.
- 7. BEGIN TERMINAL END INPUT X,Y INPUT/ OUTPUT PRINT X,Y
- 8. PROCESSING Z=(X+Y) 1 ENTRY CONNECTOR 2 TRANSFER
- 9. FLOW LINES IS YES YES CONDITION X=10 ? NO NO CONDITION BRANHING TWO WAY BRANCHING
- 10. A<B COMPARE A>B A&B I=? A=B THREE WAY BRANCHING 0 1 2 3 4 OTHERS MULTIWAY BRANCHING
- 11. An algorithms is define as a finite sequence of instruction defining the solution of a particular problem, where each instruction is numbered.
- 12. PROBLEM…………. . Draw a flow chart that swap two numbers without using third variable?
- 13. START Read input data a = a+b b = a-b a = a-b Write a,b STOP
- 14. Write a program to determine entered number is even or odd.
- 15. START Initialize X read X IF (X%2=0) print/write x is even else Print /write x is odd stop
- 16. START input the number in x NO Is YES X%2= 0 No. is No. is odd even STOP
