Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    int res;
    for(int i=0;i<4;i++)
    {
        int temp=(value>>(i*8))&0xff;
        res|=(temp<<((4-i-1)*8));
    }
    return res;
}

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