1)
a) (For Loop) Print all Number from 1 to 20
b) (For Loop) Print all Number from 10 to 20

2)
a) (For Loop) Write a program that prints all of the odd integers between 1 and 101.
b) (For Loop) Write a program that SUMS all of the odd integers between 1 and 101 and prints the sum.

3)
a) (For Loop) Write a program that prints all of the even integers between 2 and 100.
b) (For Loop) Write a program that sums all of the even integers between 2 and 100 and prints the sum.

4) (For Loop) Write a program that prints all of the multiple of 3's between 3 and 102.

5) Write a program that sums all of the integers between two input numbers, inclusive:

Enter starting number: 25
Enter ending number: 47

The sum of integers from 25 to 47 is 828

6.    Amy's Garden Emporium needs mailing labels for their shipping boxes. Write a program to print a mailing label for each box to be shipped:

How many boxes? 2

AMY'S GARDEN EMPORIUM
SUNTAN, IOWA 12345
Box Number 1 of 2

AMY'S GARDEN EMPORIUM
SUNTAN, IOWA 12345
Box Number 2 of 2

7. Write a program that asks the user for starting and ending values and then prints the following table of numbers using formatted output:

Enter starting value: 5
Enter ending value: 12

X                       X SQUARED     X CUBED
5                           25                        125
6                           36                        216
.
.
12                         144                      1728

8.    Find the sum of all the odd numbers and print a table of values giving this sum for maximum values of 1 through 50:

Number          Sum

    1            1

    2            1

    3            4

    4            4

    5            9

    6            9

   48           576

   49           625

   50           625

9.         a) The factorial of a positive number is the product of all positive integers less than or equal to the number. For example, 5 factorial (written 5!) is equal to 5 * 4 * 3 * 2 * 1, or 120. Write a program that reads a positive integer and prints its factorial:

 Enter an integer: 5
5! = 120

b) 0! is defined as 1, but all negative factorials are considered to be undefined. Modify your factorial program to correctly handle these cases:

Example 1

Enter an integer: 5
5!=120

Example 2

Enter an integer: -3
-3! is undefined.

 Example 3

Enter an integer: 0
0! = 1

10.  a) Write a program that calculates the average and total for a known number of test grades. First, read in the number of grades, then the grades.

How many grades? 12

Enter a grade: 95
Enter a grade: 75
Enter a grade: 69

The total is 1020
The average is 85.00

11.  a) Write a program that reads in letter grades for a class of 20 students. Keep track of the number of students who passed (D or better), and the number who failed (E or F).

 Enter a grade: C
Enter a grade: E
Enter a grade: B

16 students passed
4 students failed

b) Change your program to work for a class of unknown size. Stop processing grades when a Z is entered, making sure not to count the Z as a grade. Also, calculate and print the percentage of students passing and failing using formatted output: (USE The Break)

Enter a grade: C
Enter a grade: E
Enter a grade: A
Enter a grade: Z

12 students passed: 80.00 %
3 students failed: 20.00 %

 Nested For Loops

12) Use NESTED FOR LOOPS to create the Multiplication table

13. Use NESTED FOR LOOPS and 2 cout statements to produce the following output.
