26. Extract and Modify Field in a 32-bit Register

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

uint32_t update_register(uint32_t reg) {
    // Your logic here

    uint8_t mask = 0x1F;
    uint8_t field = (reg >> 10) & mask;

    if (field < 31) {
        field++;
        reg &= ~(mask << 10);
        reg |= ((field) << 10);
    }
    return reg;
}

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