1. What kind of help do you need?

?

if he's not programmer inclined he's going to hate it. If he is, he should do fine.

[MichiganVote]

2. He's not. I'll let him explain.

well, C++ is very hard for me. i'm more a guy who likes things to be A or B. if it wont work...i'm done with it. C++ is hard for me because i have to tweek everything! therefore...i have a tough time dealing with easily acomplished stuff that others breeze by with. here's a few questions for you guys that have stumped me. I dont even know what to do with them. ANY help at all would be appreciated.

1. Write a program that allows the user to enter three values. The first represents your hourly pay rate, the second represents the number of hours you worked this pay period, and the third represents the percentage of your gross salary that is withheld. The program multiplies your hourly pay rate by the number of hours worked giving the gross pay; then it multiplies the gross pay by the withholding percentage, giving the withholding amount. Finally it subtracts the withholding amount from the gross pay, giving the net pay after taxes. The program should then print to the screen, the following (gross pay, taxes withheld, and net pay).

2. Write a program that converts US dollars to pesos, yen, euros, pounds, or Canadian dollars. The program should request as input the US dollar amount and the calculate the conversion amount based on the following:

1 US dollar is worth 9.52 pesos
1 US dollar is worth 104.8 yen
1 US dollar is worth .95 euros
1 US dollar is worth .61 pounds
1 US dollar is worth 1.47 Canadian

Thanks for your time. I hope someone can help me with it.

4. do a google search for 'C++ gross pay calculations'

all kinds of stuff comes up.


then do a search for
'C++ currency converter' or similar - more stuff.




Those two searches should give you lots of sample code to work with.



Good Luck.

On another edit: leave the search as ++ and you should find lots of code.

6. Thank You nini! We'll let you know how we come out.

7. I'm having flashbacks of pulling my hair out now

:D


Good luck.. I wish the internets were available when I was in school!

8. I hear you. My son is working on your suggestions now and

he thinks he's onto something. I SOOOO appreciate your ideas.

9. I don't know if I can help

without actually doing it for him. Also, it's been a while since I've programmed (took a few courses in college), so alot of the specifics aren't there. But I'll try.

These are fairly straight-forward questions. For each of the problems there are only a few things that need to be done. First, each of the two programs needs certain introductory instructions that allow the program to run. I don't remember exactly what they are, but having a sample program in C++ will help. You just need to copy these into the program letter for letter. The most important one is that he needs to set up a "main" function, in which all the program instructions are written. Again, consult a sample to see what this looks like: "int main () { <program body> } ", or some such thing. I'll just tell the steps for the second problem, because the steps are essentially the same for both (only the mathematical formula needs to be changed). First, you need to set aside memory locations to store all the data you input. This is known as declaring variables, which must be of certain numeric types (integer, decimal, etc.) So for the second problem, you create a variable for the input dollar amount ... something like this: "float dollarAmount;" The first word is the type, which is floating point, or decimal. The second word is the variable name, which you can pick to be essentially whatever you want. This is the program's name for the memory location where the dollar amount can be stored. Then the program has to prompt the user for the dollar amount. There is a specific syntax to do this; I just don't remember what it is. Again, use a sample. Basically, the instructions are "cout" (for text output to the user) and "cin" for text input from the user. Something like this instruction stores the input value from the user in the dollarAmount variable: "cin >> dollarAmount", I think. Then an instruction must compute the appropriate foreign currency ... something like this "Yen = dollarAmount * 104.8" This multiplies the dollar amount by the exchange rate to get the new currency. It also stores that value in a variable called "Yen", which must be declared along with "dollarAmount". Then you output this value using the cout function. And you're done, at least with the Yen part. I hope this helps. If your son is still confused, send me a PM, and we'll see what we can work out. :D

10. That sounds like something our team did in either our C or Java

class! I'll see if I can find that assignment.

11. You want it in COBOL?

That was last programming I did...:hippie:

12. This isn't C++, but it is C. This is some of the code for the currency conversion

program we did:

//and Euro Dollars, as well as calculating the user's input

int main(void)
#define Franc 1.1863//Hardcoding the value of the Franc conversion

3. Learning C++ damn near killed me

I can't imagine what C+++ must be like.

[MichiganVote]

5. My mistake....it is C++ not C+++....Sorry/MichiganVote

If you have any ideas for his previous post feel free to pile on.

14. With these kinds of problems, It's Helpful To Break Them Down Into English First

Here the first problem:

Write a program that allows the user to enter three values. The first represents your hourly pay rate, the second represents the number of hours you worked this pay period, and the third represents the percentage of your gross salary that is withheld. The program multiplies your hourly pay rate by the number of hours worked giving the gross pay; then it multiplies the gross pay by the withholding percentage, giving the withholding amount. Finally it subtracts the withholding amount from the gross pay, giving the net pay after taxes. The program should then print to the screen, the following (gross pay, taxes withheld, and net pay).

Let's break it down:
Steps:
(1)Write a program that allows the user to enter three values. The first represents your hourly pay rate, the second represents the number of hours you worked this pay period, and the third represents the percentage of your gross salary that is withheld.


--You need an interface that will prompt the user to enter the data.
--You will need read in what the user entered into variables.
--You will need three variables(hourlyRate, numberOfHours, withheldPercent) to store the data and the variables must be of a type that's consistent with what's entered.


(2) The program multiplies your hourly pay rate by the number of hours worked giving the gross pay; then it multiplies the gross pay by the withholding percentage, giving the withholding amount.

-- You will need a C++ method or function called Withholding Function (I'm a Java guy) that will read in the three variables created in step one, perform the calculations, and return the withholding value to another new variable, call withheldAmount.



(3)Finally it subtracts the withholding amount from the gross pay, giving the net pay after taxes.

-- You will need a second C++ method or function that will read in hourlyRate, numberOfHours, and withheldAmount. The function will multiply hourlyRate*numberOfHours-withheldAmount and return netPay.


(4)You need to use an existing function to display netPay.

In sum, you need the following variables:
hourlyRate
numberOfHours
withheldPercent
withheldAmount
netPay

You need the following functions:
WithholdingCalc(hourlyRate,numberOfHours,withheldPercent) returns withheldAmount
NetPayCalc(hourlyRate,numberOfHours,withheldAmount) returns netPay
