Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    char *ptr = (char*)&value;
    for(int i =0; i<2; i++){
        char temp = *(ptr+i);
        *(ptr+i) = *(ptr+3-i);
        *(ptr+3-i) = temp;
    }
    return value;
}

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