Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {

    uint32_t byte3 = (value & 0xFF000000) >> 24;
    uint32_t byte2 = (value & 0xFF0000) >> 8;
    uint32_t byte1 = (value & 0xFF00) << 8;
    uint32_t byte0 = (value & 0xFF) << 24;

    return byte0 | byte1 | byte2 | byte3;
}

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