C++

Congratulations on completing your own C-language compiler, in this chapter we grumble and say something about the problems that should be noted in compiling the compiler. Some of the challenges encountered while writing the compiler. This series:

When the background program runs a problem, the detailed log is an indispensable helper, here provides a way to automatically record the log trigger point file name, line number, function name, the key is to use C99 new preprocessing identifier __va_

We know that after the DSP starts, the system will enter the reset interrupt, at this time the Reset interrupt service function is c_init00, this function is used to establish the C environment, to enter the main () function for system

Conclusion:For an object that does not have a data member, its memory unit is not 0,c++ with a memory unit to represent the existence of this instance object.If you have data or virtual functions (virtual destructors), then the corresponding memory

The Func and action are built-in delegates to C # and can no longer be defined when using delegates.(1) Func: A delegate with a return type.A delegate of type Func must have a return type, and if Func has only one argument, then it is a method that
