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:
Operation: Operation
You have been cordially invited to partake in Operation: Operation. Your mission, should you choose to accept it, is to take the two numbers and the operator given then perform the operation successfully.
Input Format
A line containing a number, operator, and another number separated by a space.
Input Sample
5 + 0.70
Output Format
A line containing a decimal/float containing two decimal places.
Output Sample
5.70
Test Cases
1. Test Case 1
-Input
1.6 - 1.4
-Expected Output
0.20
2. Test Case 2
-Input
5 * 5
-Expected Output
25.00
3. Test Case 3
-Input
5 + 0.70
-Expected Output
5.70
Note: This is C programming. All test cases must be satisfied.
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-string to 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.
