Exercise 4: Selection and loop statements
A certain professor gives 5-point quizzes that are graded on the scale 5-A, 4-B, 3-C, 2-D, 1-
F, 0-F. Write a program that accepts a quiz score as an input and prints out the corresponding
grade.
The input data must be a float numbers and between 0 and 5
Example
Input :
Quiz score: 3
Output:
The grade is C.
Exercise 4
Write an improved version of the future value program from Chapter 2. Your program will
prompt the user for the amount of the investment, the annualized interest rate, and the number
of years of the investment. The program will then output a nicely formatted table that tracks
the value of the investment year by year. Your output might look something like this:
CODE FOR SINGLE-DIGIT CALCULATOR USING EMU8086
Write a program that would accept 2 single-digit numbers num1 and num2 (0-9) and an arithmetic operator (+, - , * and /). Perform arithmetic operations entered with num1 and num2. If the operator is invalid, display "Operation Error".
Write code that performs the following input operations:
• Read an int from the keyboard and assign it to a variable named k. (Do
not print a prompt. Use the input() function without a prompt-string to
read the input.)
• Read a float from the keyboard and assign it to a variable named d.
(Do not print a prompt. Use the input() function without a prompt-
stringto read the input.)
• Read a string from the keyboard and assign it to a variable named s.
(Do not print a prompt. Use the input() function without a prompt-
string to read the input.)
After you have performed the input, on one line, print these variables in
reverse order (s followed by d, followed by k) with exactly one space in
between each. On a second line, print them in the original order (k followed by
d, followed by s) with one space in between them.

- 15. Speed Conversion ChartYour friend Amanda, who lives in the United States, just bought an antique European sports car. The car’s speedometer works in kilometers per hour. The formulafor converting kilometers per hour to miles per hour is:MPH = KPH * 0.6214In the formula, MPH is the speed in miles per hour and KPH is the speed in kilometersper hour. Amanda is afraid she will get a speeding ticket, and has asked you to write aprogram that displays a list of speeds in kilometers per hour with their values convertedto miles per hour. The list should display the speeds from 60 kilometers per hourthrough 130 kilometers per hour, in increments of 5 kilometers per hour.
