I am trying to return the max value using the max function but its not working on 3 values.
CodeBlocks Error:
error: '__comp' cannot be used as a function
The Code:
#include <iostream>
using namespace std;
int main()
{
cout << max(5, 10, 20);
}
How to return the max value between 3 values?

Use this overloaded function std::max that accepts an object of the type std::initializer_list<int>:
cout << max( { 5, 10, 20 } );
This function has the following declaration
template<class T>
constexpr T max(initializer_list<T> t);
Otherwise the compiler tries to select the function
template<class T, class Compare>
constexpr const T& max(const T& a, const T& b, Compare comp);
and issues an error.
Pay attention to that you need to include the header <algorithm>,
