Little Endian to Big Endian

Code

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

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


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