Seriously need with this c++ program. Heres the assignment and what I have for now. For some reason its saying that my inputs (cin) is an error with the equal sign or something.

Overall Assignment For this assignment you are to write a simple C++ program that will ask the user for dimensions, inner and outer temperatures, and thermal conductivity of a thick-walled cylinder, and will report the heat loss from the cylinder due to conduction. Background: Conductive Heat Transfer Through a Thick-Walled Cylinder Heat loss due to conduction through a thick-walled cylinder (e.g. a pipe) can be calculated using equations (1) and (2) below, as illustrated in Figure 1: T; T, In(r2/ri)
