vecpp :: Vec<typename, size_t>

vecpp::begin(vecpp::Vec)

template<typename T, std::size_t L>
constexpr T* begin(Vec<T,L>& v);

template<typename T, std::size_t L>
constexpr const T* begin(const Vec<T,L>& v);

Returns an iterator to the first element of the vector. This can be used directly, or indirectly through a range-based for loop.

Parameters

Argument Role
v The vector to get the iterator from

Return value

Iterator to the first element.

Example

#include "vecpp/vecpp.h"

#include <numeric>

float sum_elements(const vecpp::Vec<float, 3>& v) {
  return std::accumulate(begin(v), end(v), 0.0f);
}
