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 res=0;
    int j=24;
    for(int i=0;i<4;i++){
        res|=((value>>(i*8))&(0xff))<<j;
        j=j-8;

    }
    return res;
}

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