如何使用unsigned char分配#define

Question

我想知道可以#define分配unsigned char ??如果可以的话？

例如：

 #define ACCESS_PSS {0x32,0xFD,0x6E,0x2D}


    int main(){
    unsigned char ResponseData[100];
    for (int i = 0; i <4;i++0){

                    if (ResponseData[i+5]==ACCESS_PSS){ //how to do this???
                                cout<<5<<endl;
                                              }

ResponseData获取值，字节5 ta 8等于ACCESS_PSS

最佳方式：

const uint8_t ACCESS_PSS [4] = {0x32,0xFD,0x6E,0x2D};

if(memcmp(&ResponseData[i+5], ACCESS_PSS, 4) == 0)

替代方式（复合文字）：

if(memcmp(&ResponseData[i+5], (uint8_t[4]){0x32,0xFD,0x6E,0x2D}, 4) == 0)
