C++ mini question

Sandals

Hello I need a bit of help with a programme I basically have to assign a value for tax, which I have done here
tax = (.2*200) + (.4*hightax_pay) - tax_credits;

which is working perfect except I need another bit which says it can never be negative, as in in the instance where tax credits exceed tax,
so what should I enter

Being totally honest, I'm not giving this too much thought but the first thing that comes to mind:

Store the (.2*200) + (.4*hightax_pay) calculation as a variable {a}; and do a comparison to tax_credits {b} before you do the total tax calculation.
ie.
pseudo-code:

if(a < b) 
{ 
  // i.e. {b} = tax credits, and exceeds {a} - exit gracefully
  // exception handling
}
else 
{
  // otherwise, the calculation applies as normal..
  a - b;
}

Yes thanks my mind just drew a blank thats perfect, also one final question I have to output four variables at the end of the program on the one line with spaces, how do I do that, eg.
cout << employee_no << gross_pay << net_pay << tax;

silverside

cout << "your wages are " << wages << " and you pay tax of " << tax << endl;

should work

No I can't have any text, just the figures that's the problem, its an assignment for college.

Then delete the text...

cout << " " << wages << " " << tax << endl;
