C++ Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to C++ Framework. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.

Q 1 - What is the output of the following program?
#include<iostream> using namespace std; class abc { public: static int x; int i; abc() { i = ++x; } }; int abc::x; main() { abc m, n, p; cout<<m.x<<" "<<m.i<<endl; }
Answer : A
Explaination
The static member variable x shares common memory among all the objects created for the class.
#include<iostream> using namespace std; class abc { public: static int x; int i; abc() { i = ++x; } }; int abc::x; main() { abc m, n, p; cout<<m.x<<" "<<m.i<<endl; }
Q 2 - The operator used to access member function of a structure using its object.
Answer : A
Explaination
Just the way we use dot (.) operator to access members of the class, in similar it is used to access the members of the structure too.
Q 3 - Runtime polymorphism is done using.
Answer : C
Explaination
Virtual functions gives the ability to override the functionality of base class into the derived class. Hence achieving dynamic/runtime polymorphism.
Q 4 - Designer of C++ programming language.
Answer : D
Explaination
Q 5 - What is the full form of RTTI.
A - Runtime type identification
B - Runtime template identification
Answer : A
Explaination
Q 6 - Choose the option not applicable for the constructor.
Answer : C
Explaination
A constructor cant be overridden.
Q 7 - What is the outpout of the following program?
#include<iostream> using namespace std; main() { enum { india, is = 7, GREAT }; cout<<india<<" "<<GREAT; }
Answer : C
Explaination
0 8, enums gives the sequence starting with 0. If assigned with a value the sequence continues from the assigned value.
#include<iostream> using namespace std; main() { enum { india, is = 7, GREAT }; cout<<india<<" "<<GREAT; }
Q 8 - What is the output of the following program?
#include<iostream> using namespace std; main() { float t = 2; switch(t) { case 2: cout<<Hi; default: cout<<"Hello"; } }
Answer : D
Explaination
Error, switch expression cant be float value
#include<iostream> using namespace std; main() { float t = 2; switch(t) { case 2: cout<<Hi; default: cout<<"Hello"; } }
Q 9 - A single line comment in C++ language source code can begin with _____
Answer : D
Explaination
Two immediate forward slashes are used to comment a single line. A single can be commented by beginning with /* and should be terminated with */ , in general used for multi-line comments.
Q 10 - What is the output of the following program?
#include<iostream> #include<string.h> using namespace std; main() { char s[] = "Hello\0Hi"; cout<<strlen(s)<<" "<<sizeof(s); }
Answer : A
Explaination
Length of the string is count of character upto \0. sizeof reports the size of the array.
#include<iostream> #include<string.h> using namespace std; main() { char s[] = "Hello\0Hi"; cout<<strlen(s)<<" "<<sizeof(s); }
