Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
   uint32_t result=0;
    uint32_t mask = 0x1F << 10;
   result |=(reg&mask)>>10;
    
   if(result<31)
       result +=1;

       reg &= ~mask ;
       reg |= (result << 10);
    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
