Design ideas: First create a file, read the file, in the creation of two one-dimensional array, one store different letters, the other stores the number of letters. Count each letter first, and then select the letters that are the most frequently. Through this experiment, found that they do not understand the file, do not know how to create a file, through the Internet search, find related programs, wrote a section of the code to create a file, but the entire program is not written to complete, but also need to learn more under the class.
