Implicit rules---- When we use makefile, there are things that we often use and use very frequently, such, we compile the C/C ++ source program as the intermediate target file (in UNIX, it is [. o] file, which is [. OBJ] file ). This chapter

Implied rules————When we use makefile, there are some things we will use very often, and the use of very high frequency, for example, we compile the source program C/s + + for intermediate target files (Unix is [. o] File, under Windows is [. obj]
