  1. Flowchart Tutorial

  2. Example 1: Draw a flowchart to find the sum of first 50 natural numbers.

  3. start SUM=0 N=0 N=N+1 SUM=SUM+N no IS N==50? yes Print SUM END

  4. Example 2 Draw a flowchart to find the largest of three numbers A, B, and C.

  5. START READ A,B,C yes IS B >C ? no IS A>B ? yes IS A>C ? yes no no PRINT C PRINT A PRINT B END

  6. Example 3 Draw a flowchart for program Find the difference and the division of two numbers and display the result.

  7. START READ N1 , N2 D=N1-N2 V=N1/N2 PRINT D , V STOP

  8. Example 4 Draw a flowchart for program Print the first 10 natural number

  9. start N=1 Print N N=N+1 yes while N <= 10 no END

  10. Example 6 Draw a flowchart for program Calculate the student grade ( A,B,C,D,F)

  11. start Read Grade Grade >=90 Print A yes no Grade >=80 Print B yes no Grade >=70 yes Print C no Grade >=60 yes Print D no Print F END

  12. Example 7 Draw a flowchart for program read temperature , If temp > 0 print above freezing else below freezing

  13. start Read Temp Temp >0 yes Print“above freezing” no Print“below freezing” End

  14. Example 8 Draw a flowchart for program read (10) marks for (20) students, then print the average for each student.

  15. START studentCount=0 markCount=0 sUM=0 , avg=0 While studentCount <20 no yes STOP While markCount<10 no avg=sUM/10 yes PRINT avg READ x Increment studentCount sUM=sUM+x Increment markCount avg=0 , sUM=0 markCount=0
