要使用指针判断receivedData是否等于0x01 0x03 0x00 0x00 0x00 0x03 0x05 0xCB,可以通过以下代码实现:
```c
char receivedData[] = {0x01, 0x03, 0x00, 0x00, 0x00, 0x03, 0x05, 0xCB};
char expectedData[] = {0x01, 0x03, 0x00, 0x00, 0x00, 0x03, 0x05, 0xCB};
int i;
int len = sizeof(receivedData) / sizeof(char);
if (len == sizeof(expectedData) / sizeof(char)) {
for (i = 0; i < len; i++) {
if (*(receivedData + i) != *(expectedData + i)) {
printf("receivedData is not equal to expectedData!\n");
break;
}
}
if (i == len) {
printf("receivedData is equal to expectedData!\n");
}
} else {
printf("The length of receivedData is not equal to the length of expectedData!\n");
}
```
以上代码中,我们先定义了一个char类型的数组receivedData,来存储接收到的数据。然后定义了一个期望的数据expectedData,即0x01 0x03 0x00 0x00 0x00 0x03 0x05 0xCB。接下来,使用一个循环来检查接收到的数据是否与期望的数据一致,如果不一致,则输出错误信息。如果一致,则输出匹配成功的信息。
注意,这里使用了指针来访问数组中的元素,即*(receivedData + i)和*(expectedData + i),它们等价于receivedData[i]和expectedData[i]。
