Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
  uint32_t Shift =10;
  uint32_t Mask = 0x1F;
  uint32_t field = (reg>>Shift) & Mask;

  if(field < 31)
  {
    field = field +1;
  }
  reg = reg & ~(Mask << Shift);
  reg |= (field & Mask)<<Shift;
  return reg;

    
}

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