Weekly Pay roll

[awesomesause]

My problem arises when hours or pay rate is 0 as an input but the program does not calculate it as a 0.
I tried inputting 0 as the hours on the first 3 lines of code but after those few line the gross pay is not 0 when it is supposed to be.

this is the input:
123456789 25.5 3 40.0
234567812 15.5 4 45.0
234512345 16.3 0 60.0
123456799 15.5 3 40.0
213456782 25.5 5 50.5
123452345 17.5 2 35.0
123456321 -10.5 2 24.5
213345657 10.5 -2 45.0
123533212 17.2 3 -25.0
423556578 19.5 20 65.0
555555125 30.0 3 35.5
293049506 15.0 2 0.0
938950677 0.0 0 0.0
766445667 25.5 10 40.0
432123567 20.5 7 25.5

And this is the output

The gross pay is 736.25
The gross pay is 1828.35
The gross pay is 2448.35
The gross pay is 3133.73
The gross pay is 3126.23

[vin]

Program works fine. You just don't write to outfile when gross pay is zero.

...
	if(pay_rate == 0.0 || hours == 0.0){
		gross_pay = 0;
		outs << "The gross pay is " << gross_pay << endl;
	}
	//Find the gross pay
	else{
		gross_pay1 = 0; gross_pay2 = 0; gross_pay3 = 0; // should set to zero each time
			
		if(hours <= 40){
...

Also gross pay for first line in infile is never calculated.
