Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t value) {
    uint32_t a=0;
   for(int i=0;i<=24;i+=8){
    a|=((value>>i)&0xFF)<<(24-i);
   }
    return a;
    
}

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