Помогите написать прогу на с++

Напишите программу, которая поможет выучить таблицу умножения.
Суть программы в том, что она будет печатать на экране, например:

Затем вводится ответ. Если ответ верный, то программа печатает:
Молодец!
Если же неверный, то печатает:
Попробуй еще раз!
И задает новый вопрос.

Помогите перевести текст, только не через переводчики слишком уж они коряво переводят .
In a recent research study an average of 48 per cent of dog owners and 33 per cent of cat owners said their pets responded to their thoughts. Surprisingly little research has been done on these phenomena.
I have been investigating some of these unexplained powers of animals, powers of perception that can be grouped into three categories: telepathy; sense of direction; and premonitions.
To test these possibilities, you have to do experiments. I and my colleagues have concentrated on the phenomenon of dogs that know when their owners are coming home. Other kinds of animal telepathy can also be investigated experimentally, such as the apparent ability of dogs to know when they are going to be taken for walks. In these experiments the dogs are kept in a separate room and videotaped. Their owner, at a randomly selected time, thinks about taking the dog for a walk and then five minutes later does so. Our experiments have shown dogs exhibiting obvious excitement when their owner is thinking about taking them out, although they could not have known this by normal sensory means.
Animals' sense of direction is another hitherto unexplained power. Dogs and cats can make their way home from unfamiliar places many miles away. Even if some species have a compass sense, enabling them to detect the earth's magnetic field, this cannot explain their ability to navigate.
Animals also exhibit what we might call premonitions, for example, animals that become disturbed before earthquakes.
All three types of perceptiveness - telepathy, the sense of direction and premonitions - seem better developed in non-human species, such as dogs, than in people. Although very little research has been done, such premonitions seem to occur in the human realm too. We might have lost some of these abilities because we no longer need them: telephones and television have taken the place of telepathy; maps and global positioning systems have replaced sence of direction…

Forty-four people escaped. but the ship's cargo was lost. In the 1980s divers found the wreck. They found most of the dishes packed in tea in wooden chests and brought them to the surface.
