1,int成员变量赋值
class CTest
{
public:
CTest(void);
public:

int m_y;
};
m_x = 1;对应的汇编
mov DWORD PTR [eax], 1
m_y = 3;对应的汇编
mov DWORD PTR [eax+4], 3
2,short成员变量赋值
class CTest
{
public:
CTest(void);
public:
short m_x ;
short m_y;
};
m_x = 1;
mov WORD PTR [eax], 1
m_y = 3;
mov WORD PTR [eax+2], 3
3，unsigned char赋值
class CTest
{
public:
CTest(void);
public:
unsigned char m_x ;
unsigned char m_y;
};
m_x = 1;
mov BYTE PTR [eax], 1
m_y = 3;
mov BYTE PTR [eax+1], 3
4，float 成员变量赋值
class CTest
{
public:
CTest(void);
public:
float m_x ;
float m_y;
};
m_x = 1;
fld1
fstp DWORD PTR [eax]
m_y = 3
fld DWORD PTR
__real@40400000
fstp DWORD PTR [eax+4]
5，double成员变量赋值

m_y = 3;
fld QWORD PTR
__real@4008000000000000
fstp QWORD PTR [eax+8]
6，bool变量赋值
class CTest
