A function overload has the same function name but the number or type of arguments is different so that the corresponding method is invoked depending on the number of parameters and the type of parameter.

Emphasize one point:
#pragma packs (4)
typedef struct
{
Char buf[3];
Word A;
}KK;
#pragma pack ()
The principle of alignment is min (sizeof (word), 4) = 2, so it's 2-byte
The program compiler's special handling of the storage of the structure does increase the speed of the CPU storage variables, but sometimes it also brings some trouble, we also block out the default alignment of the variable, we can set the
#pragma pack (4)//4-byte aligned, but in fact the maximum number of bytes consumed by a single member in a struct is 2 bytes, so it is actually aligned by 2 bytestypedef struct{Char buf[3];Word A;}KK;#pragma pack ()//de-Custom byte alignmentThe
