Detailed Description

Exemplars of this class allow to systematically generate all combinations for n elements and sample size k.

Constructor & Destructor Documentation

combination_t()

combination_t::combination_t ( combination_element_t  n, combination_element_t  k  )

inline

A combination exemplar must be initialized with number of elements and sample size.

Parameters

n	Number of elements.
k	Sample size.

n()

combination_element_t combination_t::n ( ) const

inline

Returns number of elements.

Returns

Number of elements.

next()

bool combination_t::next ( )

inline
