Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // tách thành từng byte
    uint32_t byte1 = (value & 0x000000FF) <<24;
    uint32_t byte2 = (value & 0x0000FF00) <<8;
    uint32_t byte3 = (value & 0x00FF0000) >>8;
    uint32_t byte4 = (value & 0xFF000000) >>24;
    return byte1 | byte2 | byte3 | byte4;

    // Write logic to swap bytes
}

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