Question from the C++ test

Consider the following code:

class Test
{
    		private:
                		char *str;
    		public:
                		Test( char *s1 )
                		{
                            		….
                		}
                		
                	~Test()
                    	{
                            		delete str;
                	}
};
void main()
{
    		Test s(“test string”);
}

What is the correct definition of constructor Test, in order to ensure that code runs successfully?

Test( char *s1 ){
    		strcpy( str, s1 );
}

Test( char *s1 ){
    		str = new char[ strlen(s1) + 1 ];
    		strcpy( str, s );
}
