How to get the min and the max of a QList in Qt without using any iterator?

c++, qlist, qt

Solution

If you don't want iterator as result but directly the value, you may deference the result directly:

//assert(!listVal.empty());
double min = *std::min_element(listVal.begin(), listVal.end());
double max = *std::max_element(listVal.begin(), listVal.end());

And in C++17, with structure binding:

//assert(!listVal.empty());
auto [min, max] = *std::minmax_element(listVal.begin(), listVal.end());

Problem

Is there a way to get the min and the max of a QList in Qt without using any iterator ? Here is the code using iterator : ``` QList<double>::iterator min = std::min_element(listVal.begin(), listVal.end()); QList<double>::iterator max = std::max_element(listVal.begin(), listVal.end()); ```
