decimal being stored as 0
Hi, this is only the second program I have ever done in C. It is for my college class, and it is driving me crazy. I think I got it all right, but for some reason on the first two imputs, it acts like you are imputting a 0, when you are just inputing a decimal number. I can't figure out why it isn't using the decimal number you enter.
Please help if you can thanks :)
Note: it is the profrate and trate that seem to be the problem. The input values for the two are .1 for the trate, and .2 for the profrate.
When run, the results come out as if you had entered 0 for both
