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.

Answer : C
Explaination
Few characters have alternative representation and start with ??. Eg. Fro [ equivalent is ??(
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 - Pick up the valid declaration for overloading ++ in postfix form where T is the class name.
Answer : B
Explaination
The parameter int is just to signify that it is the postfix form overloaded. Shouldnt return reference as per its original behavior.
Q 4 - Designer of C++ programming language.
Answer : D
Explaination
Answer : D
Explaination
Scope resolution operator is used to resolve for the global scope of a variable if the local and global variables conflict by name.
Q 6 - Which type of data file is analogous to an audio cassette tape?
Answer : B
Explaination
As the access is linear.
Q 7 - What is the output of the following program?
#include <iostream> using namespace std; int main () { // local variable declaration: int x = 1; switch(x) { case 1 : cout << "Hi!" << endl; break; default : cout << "Hello!" << endl; } }
Answer : B
Explaination
Hi, control reaches default-case after comparing the rest of case constants.
#include <iostream> using namespace std; int main () { // local variable declaration: int x = 1; switch(x) { case 1 : cout << "Hi!" << endl; break; default : cout << "Hello!" << endl; } }
Q 8 - What is the output of the following program?
#include<iostream> using namespace std; main() { int a[] = {1, 2}, *p = a; cout<<p[1]; }
Answer : B
Explaination
as p holds the base address then we can access array using p just like with a
#include<iostream> using namespace std; main() { int a[] = {1, 2}, *p = a; cout<<p[1]; }
Q 9 - What is the output of the following program?
main() { }
Answer : A
Explaination
It is valid to have main() function empty, therefore producing no displayable output.
Q 10 - What is the output of the following program?
#include<iostream> using namespace std; main() { int a[] = {10, 20, 30}; cout<<*a+1; }
Answer : C
Explaination
*a refers to 10 and adding a 1 to it gives 11.
#include<iostream> using namespace std; main() { int a[] = {10, 20, 30}; cout<<*a+1; }
