Extract and Modify Field in a 32-bit Register

Code

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

#define CHECK_BITS 0x1F

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint8_t check_bit =  (uint8_t)((reg >> 10) & CHECK_BITS);
    if (check_bit < 0x1F ) // < 31
    {
        check_bit = check_bit + 1U;
        reg &= ~(CHECK_BITS << 10);
        reg |= (check_bit) << 10; 
    }
    return reg;
    
}

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