Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    union Data {
        uint8_t bytes[4];
        uint32_t value;
    } data;
    data.value = value;
    for(int i = 0; i < 2; i++){
       int temp = data.bytes[i];
       data.bytes[i] = data.bytes[3 - i];
       data.bytes[3-i] = temp;
    }
    return data.value;
}

int main() {
    uint32_t val;
    scanf("%u", &val);
    printf("%u", convert_endian(val));
    return 0;
}
