Help with coding

[imdjluis]

The idea of this program is to allow a small company to enter an employee's ID number, hours worked and rate of pay to determine their net pay after having a few taxes taken out. I have fixed it to where if you try to type in anything other than a number for ID, Rate and Hours it will ask you to enter that info in again, same for going through the process again. I am now trying to see if I can break the coding, and it doesn't look like it. My issue is that if I type in a decimal in for ID, it puts the next question couple lines together, so I'd like to see if someone can help me with these things:

1. How can I code it to where it appears as an invalid input and to try again if someone enters a decimal number in for the Employee ID?
2. It looks like the code has a problem with a high hourly rate and/or high number of hours work, i.e., try 50.00 for hourly rate and 170 for hours worked.
3. I need to also fix it to where someone cannot type in over 168.0 hours since that is the max hours in a 7 day week.

Thanks in advanced.

You should use getline(cin, variable);
This will insure it takes it the whole line of text the user enters. Make sure you include the <string> library.

[imdjluis]

So you're saying add
#include <string>

And can you tell me where to use getline(cin, variable);

[E l e c t r i c]

It would require you to not use a while loop, you would also need to change empID from an int to a string. Let me see if there is another way to get what you want. Give me a sec.

This is an assignment for school, so unfortunately I do have to use a DO Loop, which is why I used the loop I'm using. I can accept #include <string> and turn empID from int to string. I guess theoretically, if an employee ID has a decimal in it, it's not up to me right now to decide that it doesn't, so I'm good with that.

So really, now I just need help with #2 and #3 from my original post.

You can use a do loop still. However, your while loop wont work with the method I created. I am unsure off the top of my head how to prevent decimal entry after your numeric input. However, this is an example of how to prevent it in a string input.

#include <iostream>
#include <iomanip>
#include <limits>
#include <string>
using namespace std;

int main()

{
	int empID;
	double rate;
	double hours;
	int ans = 0;
	double OThours;
	double OTpay;
	double gross;
	double Tax;
	double Med;
	double FedTax;
	double Net;

getID:
	string id = "";
	cout << "Please enter your employee ID number: ";
	getline(cin, id);
	if (id.back() == '.') 
	{ 
		cout << "Invalid Input" << endl;
		goto getID; 
	}

	return 0;
}

Ok thanks, I'm going to leave the Employee ID part alone, I think it'll be ok for the assignment, especially since my instructions don't mention that the ID can or can't have a decimal in it. Can you help me with #2 and #3 from my original post?

The first problem I'm noticing is that the max numbers I can enter is 12.00/hr and 41 hours. If I try putting anything higher than those two numbers, it wants to break down the taxes twice. I can't see anything in my code that limits me within those numbers.
