Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    value = ((value >> 24) & 0xFF | ((value >> 8) & (0xFF<<8))| ((value << 8) & (0xFF<<16))| ((value << 24) & (0xFF<<24)));
    return value;
}

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