Extract Packet Fields from Byte Stream

Code

#include <stdio.h>
#include <stdint.h>
#include <cstring>

typedef struct {
    uint8_t start;
    uint8_t command;
    uint16_t data;
    uint8_t crc;
    uint8_t end;
} Packet;

void print_packet_fields(uint8_t *buffer) {
    // Overlay struct and print values
   // Packet *p = (Packet*)buffer; this also works
   
    Packet pac;
    // pac.start = *(buffer+0);
    // pac.command = *(buffer+1);
    // pac.data = buffer[2] | (buffer[3] << 8);
    // pac.crc = *(buffer+4);
    // pac.end = *(buffer+5);
    memcpy(&pac , buffer , 6) ;

     printf("Start: %hhu\n", pac.start);
     printf("Command: %hhu\n", pac.command);
     printf("Data: %hu\n", pac.data);
     printf("CRC: %hhu\n", pac.crc);
     printf("End: %hhu\n", pac.end);
    
//     printf("Start: %hhu\n",pac.start );
//     printf("Command: %hhu\n",pac.command );
//     printf("Data: %hhu\n",pac.data );
//     printf("CRC: %hhu\n",pac.crc );
//     printf("End: %hhu\n",pac.end );
}

int main() {
    uint8_t buffer[6];
    for (int i = 0; i < 6; i++) {
        scanf("%hhu", &buffer[i]);
    }
    print_packet_fields(buffer);
    return 0;
}
