Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
   uint32_t left_most = value & 0xFF ;
   uint32_t left_mid = (value & 0xFF00)>>8;
   uint32_t right_mid = (value & 0xFF0000)>>16;
   uint32_t right_most = (value & 0xFF000000)>>24;

    return ((left_most << 24) | (left_mid << 16) | (right_mid << 8)| right_most);
}

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