find max value 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: how to use max_element in c++ with vector

int main() 
{ 
    // Get the vector 
    vector<int> a = { 1, 45, 54, 71, 76, 12 }; 
  
    // Print the vector 
    cout << "Vector: "; 
    for (int i = 0; i < a.size(); i++) 
        cout << a[i] << " "; 
    cout << endl; 
  
    // Find the max element 
    cout << "\nMax Element = "
         << *max_element(a.begin(), a.end()); 
    return 0; 
}

Example 4: 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';
}

Example 5: c++ max and min of vector

auto it = max_element(std::begin(cloud), std::end(cloud)); // c++11
