Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    uint32_t AdditionalReg = 0;
    uint32_t Mask = 0x1F; // 0x1F = 31 -> 11111
    AdditionalReg = (reg >> 10) & Mask;
    
    if(AdditionalReg < 0x1F)
    {
        AdditionalReg ++;
    }
    reg &= ~(Mask << 10); //czyszczenie bitow rejestru 10-14
    reg |= (AdditionalReg << 10);
    return reg;
}

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