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.

Solution

Yn

Yn

>>> 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

>>> 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

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.

>>> 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

Input by user

Make sure the proper

indentation is used

Result after comparison

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.

>>> 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

Draw a flowchart for a Patient Intake Process in the clinic. Use all the texts presented below.

Patient in the system?

Patient arrives at Front Desk

Ask patient to be seated in the waiting room

Patient fill up the new patient form

Nurse ask for patient’s name and

search the database

Patient go to exam room

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 ( C0 ) 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

Substance Normal boiling point (Celsius)

Water 100

Mercury 357

Copper 1187

Silver 2193

Gold 2660

In your design :1.Identify the input2.The desired output3.Write the algorithm and pseudo code

Input –the observed boiling point of a substance in degree Celsius ( C0 )

Output- identifies the substances if the observed boiling point is within 5% of the expected boiling point

Algorithm

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 copperelse if the boiling point is between 2083to

2193 the substance is silverelse 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.

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.

Total purchases RM122.00Teacher’s discount RM

14.64Discounted total RM 107.36Sales tax RM 5.37Total RM 112.73

Total purchases RM 24.90Sales tax RM 1.25Total RM 26.15
