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
    uint16_t mask=(reg>>10)&0x1f;
    if(mask>=31)
    return reg;
    else
    {
        mask++;
        reg&=~(0x1f<<10);
        reg=(mask&0x1f)<<10;
        return reg;
    }
    
}

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