lot of functions that are common to both of them, likelog10(),acos(),cos(),exp(), etc. If you are using both of these modules in the same program, the only way to use these functions unambiguously is to prefix them with the name of the module, likemath.log10()andcmath.log10(...
In Visual Studio 2015, the compiler interprets this as a user-defined literal, but since there is no matching user-defined literal _x defined, it gives an error. C++ Copy error C3688: invalid literal suffix '_x'; literal operator or literal operator template 'operator ""_x' not found...

Such a point C is called a center of F. To get accustomed to the definition let’s see some examples below. The first two are what you would normally call stars. According to the above definition, however, all shapes in the first row are star-shaped. The two in the second row are ...
