I don't know why i am getting error help me to fix

Question

Here is my code:
#ifndef MYCLASS_H
#define MYCLASS_H

class MyClass
{
public:
MyClass();
protected:
private:
};
Error:
<stdin>:1:2: error:
unterminated conditional directive
#ifndef MYCLASS_H

Answer 1

Add #endif directive below class definition. Unlike regular if...else block which are formed by brackets, preprocessor directive #if needs to be paired with #endif

#ifndef MYCLASS_H
#define MYCLASS_H

class MyClass
{
public:
MyClass();
protected:
private:
};

#endif // add this
