Refactoring completion of a simple class

Here is a program fragment that should print "true" or "false" to the standard output depending on the result returned by a method chosen in the code. Part of the refactoring has already been done, but it needs to be completed.

# include <memory>
# include <iostream>
# define ALL_RIGHT 0

class Entity;

class TaskExecutor {
public:
    TaskExecutor() {
        entityPtr_ = new Entity;
    }

    bool performTask() {
        entityPtr_->callMethod();
        // TODO: return the correct result
    }

private:
    Entity* entityPtr_;
};

int main() {
    TaskExecutor executor;

    auto result = executor.performTask();

    std::cout << (result ? "true" : "false") << std::endl;

    return ALL_RIGHT;
}

You need to fix the constructor and the performTask method, ensure proper management of dynamic memory, and guarantee that the program outputs the correct value.
