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 = (1 << 6)-1;
    mask = mask << 10;
    uint32_t result = reg & mask;
    result = result >> 10;
    if(result < 31){
        result++;
        reg = (reg & (~mask));
        reg = reg | (result << 10);
    }
    return reg;
}

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