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
    int f = (1 << 5) - 1;
    int s =0;
     s |= ((reg >> 10) & (f));
    if(s < 31){
        s++;
        return ((reg & ~(0x1F << 10)) | (s << 10));
    }
    return reg;


}

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