C/C++封装多维数组给其他语言调用

当其他语言调用C/C++算法的接口时，需要将对应的语言的数组转换成C/C++能处理的数组。

因此，有了本文的转换函数，但是必须要求其他语言传入的数组是连续分配的。

#include <vector>
template<typename Ret>
bool FindArrayMember(void* array, std::vector<int>& dims, std::vector<int>& submarks, Ret& result)
{
	if (submarks.size() == 0 || dims.size() == 0 || (submarks.size() != dims.size()))
	{
		return false;
	}
	auto itsb = submarks.begin();
	for (auto itdim = dims.begin();itdim != dims.end();++itdim)
	{
		if (*itdim <= *itsb) {
			return false;
		}
		++itsb;
	}

	if (dims.size() == 1) {
		Ret* temp = (Ret*)array + submarks[0];
		result = *temp;
		return true;
	}
	std::vector<int> val;
	int mul = 1;
	for (int i = 0; i < dims.size(); ++i) {
		for (int j = i; j < dims.size() - 1; ++j) {
			mul *= dims[j + 1];
		}
		val.push_back(mul);
		mul = 1;
	}
	val.push_back(1);
	int step = 0;
	for (int i = 0; i < submarks.size(); ++i) {
		step += val[i] * submarks[i];
	}
	Ret* temp = (Ret*)array + step;
	result = *temp;

	return true;
}
