Transmit Float as Byte Stream Using Union

Code

#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 p;
    p.f = input;
    printf("Byte 0: %hu\n", p.bytes[0]);
    printf("Byte 1: %hu\n", p.bytes[1]);
    printf("Byte 2: %hu\n", p.bytes[2]);
    printf("Byte 3: %hu\n", p.bytes[3]);
    
    return 0;
}

Solving Approach

declare a packet type variable, assign the input to its float then print the bytes
