This is a type of exception arising in the class. We can call this
also as a standard exception.
- What is the output of this program?

int main ()
{
try
{
float* myarray= new float[125];
cout << "Memory Allocated";
}
catch (exception& excep)
{
cout << "Standard exception: " << excep.what() << endl;
}
return 0;
}

Variable will be allocated depends on the available space in the memory, If there is no space means, It will throw an exception.

int main()
{
char* p;
unsigned long int num = (size_t(0) / 3);
cout << num << endl;
try
{
p = new char[size_t(0) / 3];
delete[ ] p;
}
catch(bad_alloc &TheBadAllocation)
{
cout << TheBadAllocation.what() << endl;

As we are dividing the zero by three, it is returning 0.
- What is the output of this program?
#include <iostream>
#include <typeinfo>
using namespace std;
class shapeClass
{
public:
virtual void Virtualfunc() const {}
};
class NewTriangle: public shapeClass
{
public:
virtual void Virtualfunc() const
{
};
};
int main()
{
shapeClass shape_object;
shapeClass &Ref_shape = shape_object;
try
{
NewTriangle &Ref_NewTriangle = dynamic_cast<NewTriangle&>(Ref_shape);
}
catch (bad_cast)
{
cout << "Exception caught by bad_cast";
}
return 0;
}
