Example

// Run this code

#include <span>
#include <iostream>

void print(std::span<const int> sp)
{
for(auto it = sp.begin(); it != sp.end(); ++it) {
std::cout << *it << ' ';
}
std::cout << '\n';
}

void transmogrify(std::span<int> sp)
{
if (!sp.empty()) {
std::cout << *sp.begin() << '\n';
*sp.begin() = 2;
}
}

int main()
{
int array[] { 1, 3, 4, 5 };
print(array);
transmogrify(array);
print(array);
}

Output:

1 3 4 5
