C++ In a Nutshell

Name

operator&& function template — Performs logical and

Synopsis

template<typename T>
valarray<bool> operator&&(const valarray<T>& a, const valarray<T>& b);
template<typename T>
valarray<bool> operator&&(const valarray<T>& a, const T& y);
template<typename T>
valarray<bool> operator&&(const T& x, const valarray<T>& b);

The && operator performs logical and on each x && y, in which x is a scalar or an element of a, and y is a scalar or an element of b. When operating on two arrays, they must have the same size. The resulting array has the same size as the argument array(s). The type T must be one for which operator && is defined. As with any other overloaded operator &&, short-cut evaluation is not supported.
