This segment consists of a list of equipment that directly assistance adoption on the C++ Core Rules. This record will not be intended to be an exhaustive listing of applications

By way of example, if I need a summary of MyData I might use summary(MyData). If you'd like to do something with a certain variable in my information you utilize the object name, then the $ image, then the variable name.
