Today continue to take everyone to explain CORECLR GC, first we continue to see this gcsample, this article is the continuation of the previous article, if there is not clear, but also please turn to me to write the last essay. Below we continue:

As long as the rational use, C can still achieve unexpected results. Many friends complain that C efficiency is much worse than the Assembly, in fact, if the compiler principle of Keil C has a more in-depth understanding, it is possible to use the

definition and declaration of functions Both the declaration and the definition of a function must describe the same type, but the declaration can not write the parameter name, the definition must write the parameter name, but their
