Need a hand formatting numbers.
Here is my program it works how I would like it to but I can't seem to get formatting down. I want to round the numbers off in the dollar output. In some cases it is giving me 3 numbers in the cents column. I know there is a way to do it using floats but I can't seem to find the info on how to do it. My book isn't much help. Also in a couple cases I am setting a variable from another and I am unsure how to use ( char variable[25] ). You can see some of my variables have pointers and my teacher doesn't want me to use them yet. Thanks in advance.
