Please keep these as basic as possible so that I can understand and follow how it was done.

9. Write an application named Sum200 that sums the integers from 1 through 200. Display the running total when the program is halfway complete (after the first 100 numbers), and at the end.

13. Write a program named CountVowels that accepts a phrase from the user and counts the number of vowels in the phrase. For this exercise, count both uppercase and lowercase vowels, but do not consider y to be a vowel.

One technique that could be used is a switch statement for vowels ** must use a loop technique to move through the string; no shortcut methods not covered in the book will be allowed **

The results should look like this:

CWindows system321cmd.exe Halfway through.... after 100 numbers, sum is 4950 The sum of the integers 1 through 20e is 20100 Press any key to continue
