The first time to get this topic a bit of thinking, the feeling is not too clear, in fact, the actual list of detailed ideas is not so difficult, 1.1 points of change down the sense of thinking is very clear.

This program compared with the last program, just a few of the requirements of the topic, in fact, these with the previously learned knowledge can be completely resolved, so I feel as long as their own sense of the side is certainly not a problem, for the generation of random numbers and symbols are not explained in detail, and then I want to explain the topic.

The first is customizable, each line has several topics and each line has several topics that can be done using loops.

For repeated topics, the first generation of arrays, generating random numbers entered into the array, followed by a random number of comparisons, so into the array of numbers will not be repeated, the other there is no special idea, the feeling and the previous C + + almost.
