C++ examples for STL Algorithm:min_element
Using min_element in conjunction with a class that contains a < operator
#include <algorithm> #include <iostream> #include <vector> using namespace std; class MyClass//w ww. ja va 2 s .c o m { private: int m_Value; public: MyClass(const int value) : m_Value{ value } { } int GetValue() const { return m_Value; } bool operator <(const MyClass& other) const { return m_Value < other.m_Value; } }; int main(int argc, char* argv[]) { vector<MyClass> myVector{ 4, 10, 6, 9, 1 }; auto minimum = min_element(myVector.begin(), myVector.end()); if (minimum != myVector.end()) { cout << "Minimum value: " << (*minimum).GetValue() << std::endl; } return 0; }
