how to create function in c

processing function, code execution efficiency is not high. In response to the above problem, I think of the method of using a function pointer array to solve this problem.The concept of function pointers, mentioned in the classic tutorial of Mr. Tam Hao's C language program, is not used in most cases and ignores its existence. The function name is actually a pointer to the entry address of the function, but it is also different from the normal, such as the int*, double* pointers, see the follo

become a better const: people2 a,people_car2 b a.id b.people_id b.people_id ; Ref This type is different from eq_ref. It only uses the leftmost prefix of the index for association operations, or the index is not UNIQUE or primary key. Ref can be used for indexed columns using the = or To demonstrate that we recreate the tables people2 and people_car2 above, we still use MyISAM but do not specify the primary key for the id. Then we create a non-unique index for the id and eagle_id resp

fragmentation. If the free space in the tablespace can meet the request of the allocation area, but these spaces are scattered in several smaller idle "blocks, therefore, the table space cannot be used to meet the request (because the allocated space must come from a group of consecutive blocks. Fortunately, as long as the segment size in the tablespace should be exactly the same, the free space fragmentation of the tablespace can be easily avoided. This ensures that any idle zone in the tables
