Answer 1

StarCodes
as Jerry Hobby explained, your problem is using unescaped '\' in lines 7 and 9.

cout << "/ \" << endl;
should be
cout<<"/ \\"<<endl;

cout << "\___/" << endl;
should be
cout<<"\\___/"<<endl;

Answer 2

you can also use raw string literal

cout << R"x( your string )x""\n";

then you won't need to bother with escape characters and newlines

Answer 3

The problem is with the text. You have a backslash. That needs to be escaped because it’s special. Check this

#include <iostream>
using namespace std;

int main() {
//circle
cout << " ___" << endl;
cout << "/ \\" << endl;
cout << "| |" << endl;
cout << "\\___/" << endl;
}

Answer 4

Show us the code. The << operator should work, but we can't see what's wrong until we see your code.

Answer 5

StarCodes are you using the single character « instead of <<? It resembles the << left shift operator. However, it is not used as an operator in programming languages but can visually resemble the << symbol.
