[英]std::max with a dynamic array
I'm trying to use the std libraries as much as possible and I have a question with std::max 我正在尝试尽可能使用std库,而std :: max有一个问题
#include <algorithm>
void foo(size_t elem)
{
auto testArray = new double[elem];
for(int i = 0; i < elem; ++i)
{
testArray[i] = i;
}
auto maxElem = std::max(testArray, testArray + (elem - 1));
delete[] testArray;
}
What is the best way to pass in the arguments to the std::max function here? 将参数传递给std :: max函数的最佳方法是什么? I was hoping I could make this array behave like an iterator with a template.
我希望我可以使该数组的行为像带有模板的迭代器。
应该是max_element()
,而不是max()
。
auto maxElem = *(std::max_element(testArray, testArray + elem));
