C++函数调用约定
_cdecl约定：
参数：从右向左依次入栈
堆栈平衡：调用方平衡

#include "pch.h"
#include <iostream>

    int temp = a > b ? a : b;
    return temp > c ? temp : c;

int main()
{
    int iMax = 0;
    iMax = getMaxNumber(10, 30, 16);
    printf("iMAx = %d
", iMax);
}

push 参数一 //参数入栈顺序：从右向左依次入栈
push 参数二
push 。。。
push edx
push ecx //寄存器传递
call Fun //调用函数，在函数内进行堆栈平衡，retn XX

naked约定：
参数：从右向左依次入栈
堆栈平衡：调用方平衡
