What am I doing wrong, it's very basic C++ but gives an error?

Question

What am i doing wrong in here it gives me an error and its very very basic.

enter code here

# include <iostream>
using namespace std;
int main()
{
    string firstone = "giraffe academy";
    cout << firstone.substr(8, 3);

    return 0;
}

Please always include the exact error, as text. No images of code or errors. — Sami Kuhmonen, Mar 02 '21 at 19:48
You have forgotten to `#include `. Some compilers don't mind, but don't rely on that. — Adrian Mole, Mar 02 '21 at 19:50

You need to

# include <string>

that defines << for std::string

in the video, I watched guy did it without using include part. Can that be because of the compilers we use? – elf Mar 03 '21 at 05:44
@elf not so much a compiler as the `std` library; see the link posted in the comments for details. – Vlad Feinstein Mar 03 '21 at 17:02
