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
     uint32_t mask = 0x1F  << 10;
     uint32_t field = (reg & mask)>>10;
     if(field <31){
        field +=1;
        if(field >= 31) field=31;
     }
     reg &= ~mask;
     reg |= (field <<10);
    return reg;
}

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