Create a std::span from a Pointer and a Size

#include <algorithm>
#include <iostream>
#include <span>
#include <vector>
int main() {
    std::cout << '\n';
    std::cout << std::boolalpha;
    std::vector myVec{1, 2, 3, 4, 5};
    std::span mySpan1{myVec};
    std::span mySpan2{myVec.data(), myVec.size()};
    bool spansEqual = std::equal(mySpan1.begin(), mySpan1.end(),
                                 mySpan2.begin(), mySpan2.end());
    std::cout << "mySpan1 == mySpan2: " << spansEqual << '\n';
    std::cout << '\n';
}
