"Round 1:(Technical Part 1 ) warmup questions: i) Difference between c and c++ and talk about the features of c++? ii) virtual functions iii) abstract class

1)Write a function that crawls the hyperlinks present in a website and prints the dead pages? assuming i have been provided the following functions: vector hyperlinks_present_in_Webpage(String) bool is_page_dead(String)

2)How to write an interface in c++ ?

3)Have you worked with api's?

4)It seems you have limited yourself to curriculum . Any special reasons?

5)Tell about your 2 most challenging pieces of code you have written

6)In ds and algo have i done graph algorithms.name some

Conclusion:
any questions?

Round 2:(Technical Part 2 ) 1)what do you feel is your strongest language/favourite language? 2)how much is your experience in c++?

class parent { public: void walk() { cout<<" parent walking"; } } class child:public parent { public: void walk() { cout<<" child walking"; } } child p; p.walk;

3)What will be the output of the above code snippet? Will there be any error?

4)Will a constructor allocate memory if it throws an exception? Write a code to check the above situation if someone is not sure?

5)Difference between overriding and overloading

6. What are the components of a function's signature(choose): function name,return type ,no of arguments and their data type,sequence of the parameters?

    class parent
    {
               
         public:
     		parent(String )
    	{   
    	          cout<<" parent initialised";
    	}
    	void walk()  // consider its a virtual function
    	{
    		  cout<<"parent walking";
    	}
    }
    
    class child:public parent
    {
                   public:
    	child()
    	{
    		cout<<"child initialised";
   
    	}
    	void walk()
    	{
    		cout<<"child walking";
    	}
    }
   

   7)Indicate which of the numbered statements will compile,run and give the corresponding output

                                                                               compile(y/n)   run(y/n)  output 
   

   1 parent p=new parent(); 2 parent np=new child(); 3 child mp=new parent(); 4 child cp=new child();

   5 p.walk(); 6 np.walk(); 7 mp.walk(); 8 cp.walk();

(i)The statements that will give error how can i modify them so that the program runs and what will be the output. Assume that I cannot change the parent class. (ii) difference between writing parent p; parent p=new parent();

(iii) can I write
if( NULL == p) in place of if(p == NULL)

(iv) difference between writing parent *p=new parent(); and, parent &p=new parent();

Puzzle : the interviewer folded a square sheet and tore it in parts , then folded those parts and tore them again. gave me 10 pieces( 2 pairs of identical triangles, 2 pairs of identical quadrilaterals, two pieces of different triangles)and asked me to form a square
