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 fp = {
        .f = input,
    };

    for (uint8_t i=0; i<4; i++) {
        printf("Byte %d: %d\n", i, fp.bytes[i]);
    }

    return 0;
}
