(Randomly Creating Sentences) Write a program that uses random number generation to create sentences. The program should use four arrays of pointers to char called article, noun, verb and preposition. The program should create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article and noun. As each word is picked, it should be

Question

concatenated to the previous words in a character array that is large enough to hold the entire sentence. The words should be separated by spaces. When the final sentence is out- put, it should start with a capital letter and end with a period. The program should generate 20 such sentences. The arrays should be filled as follows: The article array should contain the articles "the", "a", "one", "some" and "any"; the noun array should contain the nouns "boy", "girl", "dog", "town" and "car"; the verb array should contain the verbs "drove", "jumped", "ran", "walked" and "skipped"; the preposition array should contain the prepositions "to", "from", "over", "under" and "on". After completing the program, modify it to produce a short story consisting of several of these sentences. (How about a random term-paper writer!)
