Hey guys,
I am writing a program which reads in 2 floating point numbers from file and write the output to a file. The multiply part is very easy, but I can't seem to figure out how to write f loat to a file.

well at first place i would like you to do the problem from the easy level . by this i mean its better to first just accept the numbers and then do the job you want to do and then add ne amount of sophistication you want to add.
