Solution 1

Create a static counter, and increment it in the Text class constructor.
If it reaches four, throw your exception.

C#

#include<iostream>

using namespace std;
class Test
{
    static int count;
public:
    Test()
    {
        count++;
        if(count==4)
        {
            throw int();
        }
        cout<<count<<endl;
    }
};

int Test::count=0;
int main(int argc, char *argv[])
{
    try
    {
        for(int i=0;i<10;i++)
        {
            Test *t1=new Test[i];
        }
    }
    catch(int)
    {
        cout<<"in catch block";
    }

    return 0;
}
