We have an array object in C++, and a value. We want to control this value have in array or not have in array. How we can do this?

A little example using std::find()
#include <array>
#include <iostream>
#include <algorithm>
int main()
{
std::array<int, 5> a1 { { 2, 3, 5, 7, 11 } };
std::cout << "8 is in a1 ? "
<< (a1.cend() != std::find(a1.cbegin(), a1.cend(), 8)) << std::endl;
std::cout << "7 is in a1 ? "
<< (a1.cend() != std::find(a1.cbegin(), a1.cend(), 7)) << std::endl;
return 0;
}
Can work with every container that implement or support begin() and end() (or better, cbegin() and cend())
