Answer 1

Not sure what character that is you put in front of the capital H, but i can say with certainty that you are missing the quotation marks around your string literals: "Hello", and "c++".

Answer 2

Do you print only 'Hello' on your code then program is should written like:-

#include <iostream>
using namespace std;

int main() {

cout <<"Hello";
return 0;
}
