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
Scope resolution (::) is not permitted to be overloaded.
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 - A protected member of the class in accessible in
Answer : B
Explaination
Only members of the derived class and the same class can access a protected member.
Q 4 - Class function which is called automatically as soon as the object is created is called as __
Answer : A
Explaination
If not provided the same, default constructor from the compiler is called automatically otherwise the programmers provided constructor gets called.
Q 5 - What is the full form of RTTI.
A - Runtime type identification
B - Runtime template identification
Answer : A
Explaination
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;
void f() {
cout<<"Hello"<<endl;
}
main() {
}
B - Error, as the function is not called.
C - Error, as the function is defined without its declaration
Answer : A
Explaination
No output, apart from the option (a) rest of the comments against the options are invalid
#include<iostream>
using namespace std;
void f() {
cout<<"Hello"<<endl;
}
main()
{
}
Q 8 - What is the output of the following program?
#include<iostream>
using namespace std;
main() {
int r, x = 2;
float y = 5;
r = y%x;
cout<<r;
}
Answer : D
Explaination
Answer Compile Error, It is invalid that either of the operands for the modulus operator (%) is a real number.
#include<iostream>
using namespace std;
main() {
int r, x = 2;
float y = 5;
r = y%x;
cout<<r;
}
Answer : B
Explaination
g++ is GNU C++ compiler for linux. Borland and vc++ (Microsoft visual c++) for windows.
Q 10 - What is the output of the following program?
#include<iostream>
using namespace std;
main() {
char *s = "Fine";
*s = 'N';
cout<<s<<endl;
}
Answer : D
Explaination
*s=N, trying to change the character at base address to N of a constant string leads to runtime error.
#include<iostream>
using namespace std;
main() {
char *s = "Fine";
*s = 'N';
cout<<s<<endl;
}
