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 - C++ does not supports the following
Answer : D
Explaination
C++ supports all the forms of inheritance.
Q 2 - Which of the following is not the keyword in C++?
Answer : C
Explaination
All the rest are valid keywords of C++.
Q 3 - In the following program f() is overloaded.
void f(int x) {
}
int f(signed x) {
return 1;
}
main() {
}
Answer : B
Explaination
No, as both the functions arguments is same and compiler ignores return type to consider overloading though different in return type.
Q 4 - Choose the Object oriented programming language from below.
Answer : D
Explaination
Q 5 - Objects created using new operator are stored in __ memory.
Answer : B
Explaination
new operator allocates memory dynamically know as Heap/free memory.
Q 6 - A C++ program statements can be commented using
Answer : D
Explaination
Both styles of commenting is available in C++.
Q 7 - What is the output of the following program?
#include<iostream>
using namespace std;
main() {
short unsigned int i = 0;
cout<<i--;
}
Answer : A
Explaination
0, with post decrement operator value of the variable will be considered as the expressions value and later gets decremented
#include<iostream>
using namespace std;
main() {
short unsigned int i = 0;
cout<<i--;
}
Q 8 - What is the size of the following union definition?
#include<iostream>
using namespace std;
main() {
union abc {
char a, b, c, d, e, f, g, h;
int i;
};
cout<<sizeof(abc);
}
Answer : C
Explaination
union size is biggest element size of it. All the elements of the union share common memory.
#include<iostream>
using namespace std;
main() {
union abc {
char a, b, c, d, e, f, g, h;
int i;
};
cout<<sizeof(abc);
}
Answer : C
Explaination
The only permitted special symbol is under score (_) in the identifier.
Q 10 - What is the output of the following program?
#include<iostream>
using namespace std;
void main() {
char s[] = "C++";
cout<<s<<" ";
s++;
cout<<s<<" ";
}
Answer : D
Explaination
s refers to a constant address and cannot be incremented.
#include<iostream>
using namespace std;
void main() {
char s[] = "C++";
cout<<s<<" ";
s++;
cout<<s<<" ";
}
