SUBJECT- IP/CS Try to complete the following exercises; the table above will help you: Activity 1: Look at the following table of operators a) Write a program that will ask the user for three integer numbers and then add these numbers together before displaying the answer. The input and output should be user friendly.

b) Write a program that will ask the user for four integer numbers and then add them together and then divide that total by 4 to show the average. The input and output should be user friendly.

c) Write a program that will ask for the total bill at the restaurant and then the number of diners who ate that meal. It will then work out how much each person should pay for an equal share of the meal.

d) Write a program that will ask the user the height and then the width of a rectangle and which will then show the area of the rectangle.

e) Alter the previous program so that it will ask for the height, width and also the depth of a box and then show the total volume of that box.

f) Write a program which will ask for the height, width and depth of a small box and then the height, width and depth of a larger box. Work out how much space is remaining around the small box when it is placed inside the bigger box. g) Write a program that will ask the user for how many sweets are in the bag. It should also ask how many people the sweets should be shared between. Use the whole number division to work out how many sweets each person should have and use the remainder division to find out how many sweets would be left remaining. For example if there are 14 sweets in the bag and this was to be divided between 3 people then the program should display “There will be 4 sweets each and there would be 2 left over. Activity 2: Below are the python commands written under ‘Type in’ will generate Python Syntax Errors mention the error under ‘What do you get?’

Type in: What do you get? print (hello world) print ”hello world” print (“hello world); Print (“hello world”) print (“Yo world, how is it going”) print (“Hello World”)

Activity 3:

a What are tokens? Explain tokens available in Brief.

b What is the difference between implicit type and explicit type conversion?

c Write a program to repeat the string ‘‘GOOD MORNING” n times. Here n is an integer entered by the user.

d Write a program to find the average of 3 numbers.

e Write a Python program to calculate the amount payable if money has been lent on simple

interest. Principal or money lent = P, Rate = R% per annum and Time = T years. Then Simple Interest (SI) = (P x R x T)/ 100.Amount payable = Principal + SI.

a.i P, R and T are given as input to the program.

f Write a program that will ask the user for three integer numbers and then add these numbers together before displaying the answer. The input and output should be user friendly.

g Write a program that will ask the user for four integer numbers and then add them together and

then divide that total by 4 to show the average. The input and output should be user friendly. Write a program that will ask for the total bill at the restaurant and then the number of diners who ate that meal. It will then work out how much each person should pay for an equal share of the meal.

h Write a program that will ask the user the height and then the width of a rectangle and which

will then show the area of the rectangle.
