// This program reads an integer, a list of words, and a character. 
//The integer signifies how many words are in the list. 
//The output of the program is every word in the list that contains the character at least once. 
//For coding simplicity, follow each output word by a comma, even the last one. 
//Assume at least one word in the list will contain the given character.
