typedef unsigned char BYTE#define assgin (A, ...)    Assginarr (A, # #__VA_ARGS__)

voidAssginarr (unsignedChar*_des, ...) {    inti =0;    Va_list apptr;    Va_start (Apptr, _des); //int* C = _des + 1; //int* D = & (_des[1]); //Auto e = sizeof (_des[0]) * (_des[0]-1); //memcpy (_des + 1, apptr, sizeof (_des[0]) * (_des[0]-1));     while(true)    {        intIvalue = Va_arg (Apptr,int); if(Ivalue = =-1) Break; _des[i++] =Ivalue;    }; Va_end (apptr);}

BYTE aaa[6] = {};

The main point is that the test data is automatically assigned rather than initialized.
Assgin (AAA, 0x04,0x14,0x24,0x34,0x15,0x06,-1);

The middle is another way. Only applies to 4-byte long data types because variable parameters default storage space 4 bytes Fixed even if the incoming byte is also cast

and _des + 1 in the actual assembly code in the array according to

Base + offset * sizeof (type) to calculate the next address even if it is passed in C + + only the first site of the array, but the result of the array and pointer + 1 is to be transformed that the pointer address operation is calculated according to base + variable address

There is a factor of 1 2 4 8 for Base address address addressing in byte (unsigned char) WORD (unsigned short) int Long that's the truth.

This factor is stored in a 8-bit sib.

7	6	5	4	3	2	1	0
Specify coefficients		Specify the variable address register			Specify Base Address register

Although the efficiency of memcpy is higher, this method is not feasible for non-4 byte length types

Easier to use for initializing array or array assignments note to specify Terminator-1
