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<<10)-1) ^ ((1<<15)-1));
    uint32_t res = (reg & mask ) >> 10;
    if(res < 31)
    res++;
    reg &= ~(mask);
    reg |= res<<10;
    return reg;
}

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