26. Extract and Modify Field in a 32-bit Register

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint16_t bits = ((reg>>10)&0x1F);
    //printf("%u\n",bits);
    if(bits<31){
        bits+=1;
        //printf("%u\n",bits);
        reg&=~(0x1F<<10);
        reg|=(bits<<10);
        return reg;
    }

    return reg;

}

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

Just retrieve the bits and checkwhether it is greater than 31 if not increment by 1 and then, clera the 10-14 bits and then append the bits.
