..刚做过，强转就行了，滴水练习题，我也在学 char data[]= {
0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x07,0x09,
0x00,0x20,0x10,0x03,0x03,0x0C,0x00,0x00,0x44,0x00,
0x00,0x33,0x00,0x47,0x0C,0x0E,0x00,0x0D,0x00,0x11,
0x00,0x00,0x00,0x02,0x64,0x00,0x00,0x00,0xAA,0x00,
0x00,0x00,0x64,0x10,0x00,0x00,0x00,0x00,0x00,0x00,
0x00,0x00,0x02,0x00,0x74,0x0F,0x41,0x00,0x00,0x00,
0x01,0x00,0x00,0x00,0x05,0x00,0x00,0x00,0x0A,0x00,
0x00,0x02,0x74,0x0F,0x41,0x00,0x06,0x08,0x00,0x00,
0x00,0x00,0x00,0x64,0x00,0x0F,0x00,0x00,0x0D,0x00,
0x00,0x00,0x23,0x00,0x00,0x64,0x00,0x00,0x64,0x00
};
// type: byte num: data
void search(int type, int num)
{
char *start = data;
int length = sizeof(data)/sizeof(data[0]);
int i=0;
while(i< length-type)
{
if(type == 4)
{
if(*(int*)&data[i] == num)
{
printf("address:%x , data:%d\n",&data[i],(int)num);
}
}else if(type == 2)
{
if(*(short*)&data[i] == (short)num)
{
printf("address:%x , data:%d\n",&data[i],(short)num);
}
}else
{
if(*(char*)&data[i] == (char)num)
{
printf("address:%x , data:%d\n",&data[i],(char)num);
}
}
i += 1;
}
}
int main(int argc, char* argv[])
{
printf("data start from:%x\n", data);
search(4,100);
return 0;
}这是没解耦的，接下来解耦的， 对其进行解耦，接口不改变
char data[]= {
