Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {

    value = ((value&0x000000FF)<<24) | ((value&0x0000FF00)<<8) | ((value&0x00FF0000)>>8) | ((value&0xFF000000)>>24);
    // Write logic to swap bytes
    return value;
}

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