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:
Instructions
The program in the Programming Example: Fibonacci Number does not check:
Whether the first number entered by the user is less than or equal to the second number and whether both the numbers are nonnegative.
Whether the user entered a valid value for the position of the desired number in the Fibonacci sequence.
Rewrite that program so that it checks for these things.
NOTES:
If an invalid number is entered for case 1 above, prompt the user to enter both numbers again.
If an invalid number is entered for case 2, prompt the user to enter a value until a valid value is entered.
the code:
#include <iostream>
using namespace std;
int main()
{
//Declare variables
int previous1;
int previous2;
int current;
int counter;
int nthFibonacci;
cout << "Enter the first two Fibonacci numbers: "; //Step 1
cin >> previous1 >> previous2; //Step 2
cout << endl;
//verify the first two values
if(previous1<0 && previous2>0)…
17. Math Tutor
Write a program that can be used as a math tutor for a young student. The program
should display two random numbers to be added, such as
247
+129
The program should then pause while the student works on the problem. When the
student is ready to check the answer, he or she can press a key and the program will
display the correct solution:
