How to print in C++ " \ " как

Question

Помогите, не знаю как его вывести

Answer 1

cout << is the command to print it,
(cin >> is an input)

a lot of programmers use the namespace std, because they then don't have to call always the static function, just the name;
and the escape character is \ (likely in most of the programming languages)
the entry point is the main function
and the return 0 means: is there were any errors? (0 = False, so it went properly) (if there is an error, it will return someting)

withuout using namespace std:

#include <iostream>

int main() {
std::cout << "\\";
return 0;
}

with using namespace std:

#include <iostream>
using namespace std;

int main() {
cout << "\\";
return 0;
}

I hopoe this helps
