This section presents you various set of Mock Tests related to C++ Framework. You can download these sample mock tests at your local machine and solve offline at your convenience. Every mock test is supplied with a mock test key to let you verify the final score and grade yourself.
C++ Mock Test I
Q 1 - The default access specifer for the class members is
Only the class member variables constitutes as the size of the class or its object.
#include<iostream>
using namespace std;
class abc {
void f();
void g();
int x;
};
main() {
cout<<sizeof(abc)<<endl;
}
Q 8 - 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;
}
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;
}
mutable is storage specifier introduced in C++ which is not available in C. A class member declared with mutable is modifiable though the object is constant.
Q 22 - The following operator can be used to calculate the value of one number raised to another.
