how to find the max element in a vector c++ code example

Example 1: maximum in vector

*max_element(a.begin(), a.end());

Example 2: max of a vector c++

cout<<*max_element(a.begin(), a.end())<<endl;

Example 3: c++ max and min of vector

#include <iostream>
#include <algorithm>

template <typename T, size_t N> const T* mybegin(const T (&a)[N]) { return a; }    
template <typename T, size_t N> const T* myend  (const T (&a)[N]) { return a+N; }

int main()
{
    const int cloud[] = { 1,2,3,4,-7,999,5,6 };

    std::cout << *std::max_element(mybegin(cloud), myend(cloud)) << '\n';
    std::cout << *std::min_element(mybegin(cloud), myend(cloud)) << '\n';
}
