Stack information for function calls

/*
1, stack on the heap, the address of the stack is reduced, the heap address is increased.
2, the parameters of the method on the stack, the parameters are from right to left into the stack, why?
Mainly to solve the problem of variable parameters, from right to left into the stack, the top of the stack is the first parameter,
The first argument indicates the number of arguments, or the number of arguments (the formatted string for printf).
From the top of the stack, you can traverse these parameters.
3, PA itself is also allocated on the stack, PA address is smaller than a address, PA content is a address
4, the PPA itself is also allocated on the stack, the PPA address is smaller than the PA address, the content of the PPA is PA address
5, stack on the array tmp, equivalent to cut out 8 bytes on the stack, TMP points to the top of the stack, the address is the smallest, from the top of the stack to high address
There are 8 bytes, copy "abcdef" (7 bytes, including null) into these 8 bytes, a at the top of the stack, the least address
*/
void Test (int a, int b)
{
int* PA = &a;

int** PPA = &pa;

Char tmp[8] = "abcdef";
}
