The C ++ MCQ will allow you to test your general knowledge, from beginner to more advanced level!
Specifically, it highlights your level of proficiency in the following areas: coding concepts, such as command line arguments, pointers, and memory management. So we will see:

Pointers (char pointers, pointer arithmetic)
Memory allocations / deallocation
Classes - constructors, object creation, deletion, initialization list
Concepts OOPs - Inheritance / Polymorphism

This test consists of 20 questions randomly selected from a database of 36 questions in C++.Discover all our interview questions and answers here

Sample question

Consider a class MyType which defines a public function isType() as:

       	int isType (MyType& obj)
       	{
     	          	return (&obj == this) ? 1 : 0;
       	}

What is the output of the following? Object ‘obj’ of MyType is allocated statically and a pointer variable ‘objptr’ of type MyType is declared.

        	objptr = &obj;
 
        	if ( objptr->isType(obj) )
	                	std::cout << "&obj and invoking object match!!!" << std::endl;
        	else
	                	std::cout << "&obj and invoking object do not match!!!" << std::endl;
