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
    uint32_t field = (reg >> 10) & 0x1F;
    if ( field >= 31 ) return reg;
    else 
    {
        field +=1;
        return (reg & ~(0x1F<<10)) | (field<<10);
    }
}

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