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