Serialized Data Buffer

Code

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

void build_packet(uint8_t command, uint16_t value, uint8_t status, uint32_t checksum) {
    uint8_t buffer[10];
    uint8_t* byte_value=(uint8_t*)&value;
    uint8_t* byte_checksum=(uint8_t*)&checksum;
    buffer[0]= 0xA5;
    buffer[1]=command;
    buffer[2]=*byte_value;
    buffer[3]=*(byte_value+1);
    buffer[4]=status;
    buffer[5]=*(byte_checksum);
    buffer[6]=*(byte_checksum+1);
    buffer[7]=*(byte_checksum+2);
    buffer[8]=*(byte_checksum+3);
    buffer[9]=0x5A;

    for(int8_t i=0;i<10;i++){
        printf("%d ", buffer[i]);
    }

    // Your logic to fill buffer
    // Then print buffer
}

int main() {
    uint8_t cmd, status;
    uint16_t val;
    uint32_t crc;

    scanf("%hhu %hu %hhu %u", &cmd, &val, &status, &crc);
    build_packet(cmd, val, status, crc);
    return 0;
}
