Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    uint8_t* a,b,c;
    a=(uint8_t *)&value;
    b=*a;
    *a=*(a+3);
    *(a+3)=b;
    b=*(a+1);
    *(a+1)=*(a+2);
    *(a+2)=b;

    return value;
}

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