Extract and Modify Field in a 32-bit Register

Code

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

uint32_t CLEAR_BIT(uint32_t reg,uint32_t pos,uint32_t len)
{
    uint32_t mask=(((1u<<len)-1)<<pos);
    reg&=(~mask);
    return reg;
}

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint32_t mask =(0x1F<<10);
    mask&=reg;
    mask>>=10;
    if(mask<31)
    {
        mask++;
        mask<<=10;
        reg=CLEAR_BIT(reg,10,5);
        reg|=mask;
    }
    return reg;
}

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