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* floatPacket;
    floatPacket->f = input;

    for(int i = 0; i < 4; ++i)
    {
        printf("Byte %d: %d\n", i, floatPacket->bytes[i]);
    }
    return 0;
}

Solving Approach

1. Store the input float into the union's float number
2. Access the union's byte array member to get the 4 bytes
3. Print each byte in order from index 0 to 3
