Hi,
Seems nice now. At least you've got the basics of how to write psudo code
before you program it. Keep up your effort.
As for the output part, a nice trick is to put the calculation as part of
the output, such as:
Output should be, "The commission rate is " << the calculation (sales times
commission rate) << "per whatever."
In C++:
cout << "The commission rate is " << sales*rate << " per month." << endl;
And that's it. Hope this helps...
Cheers,
Joseph

Here is another attempt, hopefully I am getting the concept of an algorithm.
Let me know.
The following contains pseudo code, as well as algorithm and two desk
checks.
Output: displays the commission on screen.
Input: the salesperson's sales and commission rate.
Processing: When the program is compiled, the user should be able to
multiply someone's current sales rate by the commission rate, which is
currently 10%. If the commission rate changes, just substitute 10% with the
new rate when entering the calculations. This should give the user a sales
person's commission rate after the person's sales rate is entered.
Algorithm:
1. Ask user to enter a sales and commission rate.
2. Store data into two separate variables, one for commission rate and one
for sales rate.
3. Multiply the data in the variables.
4. Output the result back to the user.
Desk-check 1:
2000*.10 = 200. Correct.
Desk-check 2:
5000*.06 = 300. Both Desk-checks Succeeded.
