I am invoking a C/C++ program (exe) from C#, I want to return a float value from my C/C++ to the C# code, I have the exe code which writes file a for a single value, instead I want to return that value to C#. How can I do that?

You could output the result of your C/C++ program to the standard output, and then parse it with C# after the invokation.

Or if your program is called a lot a time, maybe a better solution would be to let it run and communicate with your C# program through local sockets. C# program may send request by network and get the result back.
