it. The program demonstrates both of the overloaded forms where one prints the element with maximum value in a vector and another using a compare function to find the pair element with maximum value in a map. The compare function compares the two pairs on the basis of their second arguments...

The max_element function in C++ is used to find the maximum element from a range of elements specified by the start and end iterators. It returns an iterator pointing to the first occurrence of the maximum element in the given range. Syntax: template<typenameForwardIterator> ForwardIteratormax_...
(function template) minmax_element (C++11) returns the smallest and the largest elements in a range (function template) max returns the greater of the given values (function template) ranges::max_element (C++20) returns the largest element in a range ...

The function "del_max(num)" return 0 directly , because before you call this function. All elements are deleted. There are no elements, so "if" will not execute at all. First of all, int pop(int& n) just deletes first element ,that's true,but you put this function to conditional...
