Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    return ((value>>24)&0xff) | ((value>>8)&0xff00) | ((value<<8)&0xff0000) | ((value<<24)&0xff000000);
}

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