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 = (reg & 0x1F <<10);
    uint32_t new_reg = (reg & mask ) >> 10;
    //printf("%u \n",new_reg);
  //  reg = ~(reg & 0x1F);
    if(new_reg < 31){
        new_reg += 1;
    }
    reg &= ~mask;
    reg = (reg | ((new_reg)<< 10));
    return reg;
}

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