Linear Interpolation C code for X and Y axis - compile errors

[Paul McKenzie]

Thanks Paul. Will do.

I can't find any topics on the "<<" I am using. How do these normally work?

Well, here may be more confusion between C and C++.

In C++, there is a concept called operator overloading. This means that you can take an operator, for example, the "+", "-", "<<", etc, and define different meanings for them, depending on the type of arguments that are used with the operators. If the "<<" is not overloaded, it is the "shift-left n bits" operator. However for streams, whenever a "<<" is used "<<" takes on a different meaning, which is "stream the data to x".

In 'C', there is no such thing as operator overloading. Therefore the << has one and only one meaning -- shift left n bits.

So if you mean "<<" with respect to C++ streams, then there is plenty of topics on this, since streams are a core topic in C++.
