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
    uint8_t temp = (((((1 << 5) - 1) << 10) & reg) >> 10);
    if(temp < 31){
        temp++;
        reg &= (~(((1 << 5) - 1) << 10));    
        reg |= (temp << 10);
    }
    return reg;
}

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