Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes

    uint32_t result = (
        ( (value >> 24)  & 0x000000FF) | 
        (  (value >> 8) & 0x0000FF00) | 
        ( (value << 8) & 0x00FF0000) | 
        ( (value << 24) & 0xFF000000)
    );

    return result;
}

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