Questions:What potential problems can arise from typecasting a base class pointer into a derived class pointer so that the derived class's member functions can be called?
Answers: Syntactically this is allowable. There is always a possibility of a base pointer actually pointing to a base class. If this is typecast to a derived type, the method being called may not exist in the base class. Therefore, you would be grabbing the address of a function that does not exist.

They are otherwise functionally equivalent.
Questions:I have declared a derived class from a base class, but I can't access any of the base class members with the derived class function.Answers:Derived classes DO NOT get access to private members of a base class.In order to access members of a base class, the base class members must be declared as either public or protected. If they are public, then any portion of the program can access them. If they are protected, they are accessible by the class members, friends, and any derived classes.Questions:How can I use the Paradox Engine with C++?,Answers:Because the Paradox Engine functions are all compiled as C functions you will have to assure that the names of the functions do not get "mangled" by the C++ compiler. To do this you need to prototype the Engine functions as extern "C". In the pxengine.h header file insert the following code at the lines indicated.
/* inserted at line # 268 */
#ifdef __cplusplus
extern "C" {
#endif
/* inserted at line # 732, just before the final #endif */
#ifdef __cplusplus
}
#endifQuestions:I have a class that is derived from three base classes. Can I insure that one base class constructor will be called before all other constructors?Answers:If you declare the base class as a virtual base class, its constructor will be called before any non-virtual base class constructors. Otherwise the constructors are called in left-to-right order on the declaration line for the class.Questions:Are the standard library I/O functions still available for use with the C++ iostreams library?Answers:Yes, using
#include
functions such as printf() and scanf() will continue to be available.Questions:When debugging my program in Turbo Debugger, I notice that none of my inline functions are expanded inline. Instead, they are all done as function calls.Answers:Whenever you compile your program with debugging information included,no functions are expanded inline. To verify that your inline functions are indeed expanding inline, compile a module with the -S flag of the command-line compiler, then examine the .asm file that is generated.

Answering to any number of names; Conga ant, bullet ant, 24 hour ant, lesser giant hunting ant, the one thing consistent is the pain they cause. In their natural range from Nicaragua to Paraguay, a single stink is likened to being shot with fiery waves of pain which continue unabated for up to 24hrs. It is no wonder then that a sting by a bullet ant is rated a 4+ on the Schmidt pain index, the highest of any insect. Though apparently some tribes, notably the Satere-Mawe of Brazil have put this dubious benefit to their advantage. They gather up a large number of these ants, up to 100 and then sew them into a glove, stingers facing inwards. This is then presented to a boy of the tribe. In order to graduate to manhood he must don the glove and leave it on for a set period of time without crying out. This process is repeated, sometimes 20 times until the tribe is satisfied and the boy has become a man. Fortunately there are other uses and the poneratoxin is currently being studied in modern medicine as a voltage gated sodium channel inhibitor which blocks synaptic transmission in insects though it acts as a smooth muscle agonist in mammals.
These are the largest of the Ponerine ants achieving lengths of 20-30mm long. They display little variation between castes, workers displaying variation only insofar as a normal distribution curve with no specialization. They make nests at the base of trees and forage on the surrounding trees, climbing into the canopy to search for nectar sources and small invertebrates. If they feel their nest is being threatened they release a musky odor and stridulate from a pair of organs in the thorax.Found during a night hike in kanuku mountains. For a greater selection of photos which include different angles and species ask by pm to be added to my friend's list.
Yesterday the tire flew off my minibus, I cut the head off a pit viper and I was banned from a commercial flight by associating with a narco-trafficker. Today I am bushwhacking through the jungle in the remote trail-less backwaters of Guyana, waist deep in water and praying to make it through the rest of the day alive. What will tomorrow bring? God only knows. The adventure starts here- pbertner.wordpress.com/.
ARC answers LEHIGH’s challenge to remove 4500sq feet of transite panels comprising the outer skin of the concrete company’s 120ft tall smelter. Transite is an asbestos and concrete mix that was used extensively in the 1960s and 1970s. The panels were removed to make room for new equipment at the state-of-the-art cement manufacturing facility. The asbestos abatement removal project was completed on-time and on-budget.

My guess at this (Guess where) was no long. It's been a few months since anyone else has had a guess, so I'd take that as having given up. Unfortunately, Steph didn't know her way around the Northside well enough to describe where exactly it was. Once she showed me, I wanted to slap myself silly. I've driven right past this hundreds of times. It's right there on the corner of Gen Robinson and Anderson (aka 9th St). This warehouse is L-shaped, leaving a small gravel lot on the actual corner, with the warehouse surrounding it.

The answer - digital. This was the first Instagram photo I ever took back in April 2013, and enlisted the help of my old Polaroid Cool Cam from 1998 to try and make this look a bit older than you'd first presume. In fact my other hand is holding my smartphone in front of me, and it's that which took this picture.
This is the end result of me asking someone very politely to leave me alone. Having to turn off my phone and take this one, briefly, off the hook.
Apparently I'm impossible to love.

Explosions have been reported across Caracas, Venezuela as an apparent U.S. bombing campaign has begun targeting the country. This war is not about drug trafficking, it is not about democracy -- it is about stealing Venezuela's oil and dominating Latin America. It is an outrageous escalation in a campaign of murder in international waters and piracy targeting civilian ships trading with Venezuela.
