Bitwisebitsinik piffissa nassiussineq, C++-imi, variable takorneq bitsinik pisinnaanngaatsiannik, struct-imik takujuk. 
Nuannaarernerani: 
```c
struct Ilisarnissaq {
  unsigned int kingorna: 1;
  unsigned int niaqorneq: 3;
  unsigned int erfalasoorneq: 4;
};
```
Tassa allakkaat aallaqqaataq. Peqqutaallat:

```
struct MyStruct {
   unsigned int flag : 1;   // 1 bit
   unsigned int value : 15; // 15 bits
};
```

Tassa ukiumoortumik "flag" suliaq uku allakkaat 1 bit imalt., "value" suliaq uku allakkaat 15 bit imalt.
