Bog'liq Tiplarni dinamik tarzda-fayllar.orgcshift() - berilgan son qiymat bo‘yicha indeks asosida massivni aylana shaklida surib yangi massiv qaytaradi. Agar son musbat bo‘lsa chapga suriladi, manfiy bo‘lsa, o‘nga suriladi.
6.3-dastur. shift() va cshift()dan foydalanish.

Valarray ning standart amallari
|
valarray operator+() const; valarray operator-() const; valarray operator~() const;
valarray operator!() const;
|
Valarray tiplari ustida amallar:
|
valarray& operator*= (const valarray& rhs); valarray& operator/= (const valarray& rhs); valarray& operator%= (const valarray& rhs);
valarray& operator+= (const valarray& rhs);
| |
valarray& operator-= (const valarray& rhs); valarray& operator^= (const valarray& rhs); valarray& operator&= (const valarray& rhs); valarray& operator|= (const valarray& rhs); valarray& operator<<= (const valarray& rhs);
valarray& operator>>= (const valarray& rhs);
|
Valarray tipi va odatiy oddiy tiplar ustida amallar:
|
valarray& operator*= (const T& val); valarray& operator/= (const T& val); valarray& operator%= (const T& val); valarray& operator+= (const T& val); valarray& operator-= (const T& val); valarray& operator^= (const T& val); valarray& operator&= (const T& val); valarray& operator|= (const T& val); valarray& operator<<= (const T& val);
valarray& operator>>= (const T& val);
|
Yuqorida keltirilgan operatorilar Valarray sinfining funksiyalari hisoblandi.
Valarray tiplari bilan bajariladigan amallarni qayta aniqlash mumkin. Bunda birinchi amal Valarray tipi = Valarray tipi * Valarray tipi, ikkinchi amal Valarray tipi = oddiy tip * Valarray tipi, uchinchi tip Valarray tipi = Valarray tipi* oddiy tip ketma ketligi asosida aniqlangan.
[*] - amalini qayta aniqlash:
|
template valarray operator* (const valarray& lhs, const valarray& rhs);
| |
template valarray operator* (const T& val, const valarray& rhs);
| |
template valarray operator* (const valarray& lhs, const T& val);
