In Qt, finding the minimum or maximum value in a QList or QVector can be frustrating sometimes and it also will complicate things when you just want a quick and simple minimum and maximum. Use the pieces of codes below to get them with a single line of code.
Make sure you add the following to your include list:
#include <algorithm>It is assumed that you have a vector called vec which contains double values.
Finding the minimum value in a vector of double values or QVector<double>
double min = *std::min_element(vec.constBegin(), vec.constEnd());
Finding the maximum value in a vector of double values or QVector<double>
double max = *std::max_element(vec.constBegin(), vec.constEnd());
