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
    uint32_t result = (reg >> 10) & 31;
    if(result < 31){
        result = result + 1;
    }
    reg &= ~(31 << 10);
    reg |= ((result & 31) << 10);

    return reg;
}

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