Extract and Modify Field in a 32-bit Register

Code

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

typedef union
{
    struct 
    {
        uint32_t dummy_low : 10;
        uint32_t value : 5;
        uint32_t dummy_high : 17;
    } Bits;
    uint32_t value;
} Register32;

uint32_t update_register(uint32_t reg) {
    // Your logic here
    Register32 reg_bits;
    reg_bits.value = reg;

    reg_bits.Bits.value = (reg_bits.Bits.value < 31) ? reg_bits.Bits.value + 1 : reg_bits.Bits.value;
    return reg_bits.value;
}

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