initial values for static variables are evaluated during compilation and burned into the data section of the executable. Zero runtime overhead, early problem diagnosis, and, as we will see later, safe. This is calledconstant initialization. In an ideal world all static variables are const-initial...
Prerequisite: Storage classes in CAutomatic (auto) and static both are the keywords which are used under the storage classes, and they define the scope, lifetime, default value and memory segment of the variables.Automatic ('auto') variable...

The invention belongs to a numerically controlled rotary workbench, and relates to a variable constant-current static pressure guide rail and a control method thereof, in particular to a static pressure guide rail with large bearing capacity change range and small static pressure buoyancy change. The...

In general, dynamic means energetic or forceful, while static means stationary. In computer terminology, dynamic usually means capable of action or change, while static means fixed. The termsdynamicandstatichave a variety of applications, so their processes and differences depend on the system they ...
