Finally I got an answer by one of similar threads in this forum... The following code worked... Lets say,

    public:
    char str[1000];
    A()
    {
        strcpy(str,"Default string");
    }
    A(const char* s)
    {
        strcpy(str,s);
    }
};

void * operator new (unsigned size, char const * file, int line)
{
    cout << "File = " << file << endl;
    cout << "Line = " << line << endl;
    return( malloc(size));
}
#define new new(__FILE__, __LINE__)
int main()
{
    A *a = new A("Leak");
    printf("%s",a->str);
    delete a;
    return 0;
}
