Objectives:

Loops

Validating the range

switch statement

Program: Write a C program to prompt the user for a whole number between 3 to 10. Present a menu of options and prompt the user to select an option. Use the switch statement to carry out the selected option. The menu of options is:

Menu of Options:

Display all the numbers from 1 to num.

Display all the even numbers from 1 to num.

Compute the sum of 1 + 2² + 3² + . num².

Display numbers in reverse order from num to 1.

Compute num!

End the program.

Follow the steps in the main function.

int main()

{

// declare variables:

int num;

int option = 0;

// declare more variables as needed.

// Prompt the user for a whole number.

Validation: Validate the range of the users input in a loop (while loop or do-while loop). Keep prompting the user until the user enters a number between 3 and 10 both inclusive.

// Display the menu of options (see above).

// Prompt the user to select an option. Read it into variable option.

// Use the switch statement to process the selected option.

// Option-1: Write a loop to display numbers from 1 to num..

// Option-2: Write a loop to display the even numbers from 1 to num.

// Option-3: Write a loop to add up squares of all the numbers from 1 to num. Display the sum.

// Option-4: Display numbers in reverse order, num to 1.

// Option-5: Compute num factorial = 1 * 2 * * num

// Option-6: Thank the user and end the program.

// default: display Invalid option.

_getch();

return 0;

}

BONUS: Rerun the program so that the user can choose different options for the same input number. The rerun stops when the user selects option #6.

Grading chart:

Points	Criteria
	Intro. Comments as specified. (-1 if missing)
	Variable declarations
2	Prompt - read a whole Validate the range in a loop = 2
2	Display the menu of options.
	Prompt the user and read the selected option
16	switch statement to process the option Option-1 = 2 Option-2 = 2 Option-3 = 3 Option-4 = 3 Option-5 = 3 Option-6 = 1 Default = 2
BONUS	Rerun the program = 2

Penalties: Programs with compile errors will not be graded.
