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 mask=0x1F << 10;
  uint32_t field=(reg & mask) >> 10;
  if (field < 31){
    field +=1;
  }
  reg &=~mask;
  reg |=(field <<10);
    return reg;
}

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