Question

from the book "starting out with c++ from control structures through objects." programming challenge 5.15= display a weekly payroll report. ask the user for the employee number, gross pay, sales tax, federal tax, and fica holdings. loop terminates when 0 is entered for the employee number. the output should be totals for gross pay, sales tax, fed tax, dica holdings and net pay.

Your checks (you should have 5) for input validity should allow for users entering incorrect data more than once. In addition to the checks listed in the book, your program should also confirm that the gross pay is not negative. Your three checks for individual taxes should not allow the tax to be greater than the gross pay or to be a negative number. Your program should also count the number of employees entered. You may assume that at least one employee will be entered.

using namespace std;
int main()
{int id,count=0;
int state,federal,FICA,gross,tgross=0,tstate=0,tfederal=0,tFICA=0;

cin>>id;
while(id<0)
{cout<<"Invalid entry - re enter ";
   cout<<"Enter employee id(0) to exit: ";
