2. Problem : At Kiddy School, the teachers used the A, B,C for grading the students’ works. If the student get an A, then the teacher will print “Excellent” and if the student get B, the teacher will print “Good”. For students that get C, the teacher will print “Work Harder”. Given the problem above, design a solution using flowchart.

3. Solution Y n Y n

4. >>> grade=raw_input('enter student grade') enter student gradeA >>> if grade =='A':... print "Excellent"... elif grade =='B':... print "Good"... else:... print "Work Harder"... Excellent Input is string therefore use raw_input function User input A String –characters is compared lexicographically order, hence must put capital letter result

5. >>> grade =raw_input('enter student grade ') enter student grade a >>> if grade=='A' or grade =='a':... print 'excellent'... elif grade =='B' or grade =='b':... print 'good'... else:... print 'work harder'... excellent ‘a’ and ‘A’ have two different values. To handle input either in capital letter or small letter, the condition is joining with ‘or’ operator

6.  Problem: Your instructor asked you to design a program that can receive two input number (assumed that both number are not the same) and determine the larger of the two. Design a flowchart the problem above.

8. >>> a=input('input the first integer') input the first integer2 >>> b= input('input the second integer') input the second integer3 >>> if a > b:... print a... else:... print b... 3 Input by user Make sure the proper indentation is used Result after comparison

9. Problem: Your instructor asked you to design a program that can take 3 input and determine the largest of three input integers. Draw flowchart and write Python code for the problem above.

11. >>> a=input(' enter the first number :') enter the first number :2 >>> b=input(' enter the second number :') enter the second number :3 >>> c=input ('enter the third number :') enter the third number :1 >>> if a > b:... if a> c:... print a... else:... print c... elif b > c:... print b... else:... print c... 3

16.  The table below shows the normal boiling points of several substances. Design a program that prompts a user for the observed boiling point of a substance in degree Celsius ( C 0 ) and identifies the substances if the observed boiling point is within 5% of the expected boiling point. If the data input is more than 5% higher or lower than any of the boiling points in the table, the program should output the message Substance unknown

17. SubstanceNormal boiling point (Celsius) Water100 Mercury357 Copper1187 Silver2193 Gold2660 In your design : 1.Identify the input 2.The desired output 3.Write the algorithm and pseudo code

18.  Input –the observed boiling point of a substance in degree Celsius ( C 0 )  Output- identifies the substances if the observed boiling point is within 5% of the expected boiling point  Algorithm

19. Input the boiling point if the boiling point is between 95 to 100 then the substance is water else if the boiling point is between 337 to 357 the substance is mercury else if the boiling point is between 1128 to 1187 the substance is copper else if the boiling point is between 2083to 2193 the substance is silver else if the boiling point is between 2527 to 2650 the substance is gold else if the boiling point is more than 2650 and lower than 95 the substance is unknown.

20.  Keith’s Sheet Music needs a program to implement its music teacher’s discount policy. The program is to prompt the user to enter the purchase total to indicate whether the purchaser is a teacher. Music teachers receive a 10% discount on their sheet music purchases unless the purchase total is RM100 or higher. In that case, the discount is 12%. The discount calculation occurs before addition of the 5% sales tax. The sample outputs are as below: two output, 1 for teacher another one is not teacher.

21. Total purchases RM122.00 Teacher’s discount RM 14.64 Discounted total RM 107.36 Sales tax RM 5.37 Total RM 112.73 Total purchases RM 24.90 Sales tax RM 1.25 Total RM 26.15 What you need to do? 1.Analyze the problem - Identify input -Identify output -Identify formula 2.
