I need some help I am not sure how to program this. I am to post to be a employer that is interested in determining the pay an individual is to recieve. The number of hours and pay rate should be read in. If the hours are over the 40 the rate is "time and a half" for those hours over. Then I have to report the total earned amount, earned for regular hours and the amount earned for overtime hours. But this is what I have so far. The program is able to calculate the standard time but the overtime is incorrect. I want the user to be able to enter the hour and the rate. But I do not how to do that I only know how to assign it.
