[Anonymous]

Я получаю проект от
https://github.com/cchuahuico/cool-compilerобразной />
class Main inherits SuperClass {
main(): Object {{
out_string("Enter an integer greater-than or equal-to 0: ");

let input: Int in
if input < 0 then
input
-- out_string("ERROR: Number must be greater-than or equal-to 0\n")
else {
-- out_string("The factorial of ").out_int(input);
-- out_string(" is ").out_int(factorial(input));
factorial(input);
}
fi;
}};

factorial(num: Int): Int {
if num = 0 then 1 else num * factorial(num - 1) fi
};
};

class SuperClass {
out_string(str:String){};
};

При составлении этого с Mingw у меня есть эта ошибка < /p>
