Hi Everybody I am new to C++ and have a problem from the book my instructor gave that I am having some problems with. I am sure you guys are all familiar with the "mortgage calculator" here is my code. The Errors I am getting are as follows. I have been working on this for a few days now and any help would really be great!!
