72. Transmit Float as Byte Stream Using Union

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

typedef union {
    float f;
    uint8_t bytes[4];
} FloatPacket;

int main() {
    float input;
    scanf("%f", &input);

    // Fill union and print 4 bytes
    FloatPacket pack;
    pack.f = input;
    for(uint8_t x=0;x<4;x++)
        printf("Byte %d: %u\n", x, pack.bytes[x]);
    return 0;
