Write assignment statements that perform the following operations with int variable i, double variables d1 and d2, and char variable c.
A) Add 2 to d1 and store the result in d2.B) Multiply d2 times 4 and store the result in d1.C) Store the character 'K' in c.D) Store the ASCII code for the character 'K' in i.E) Subtract 1 from i and store the result back in i.
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.
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:
