Hi
I would like know if the sloution of this task right or not?
If its wrong please comments it.
I will be very thankful.
In this task, you should show that you can solve problems using Top Down Design and construct programs in which their own defined methods exist.
Use Top Down Design to develop a program to assess the readability of a text string consisting of one or more sentences. The program's users to enter a text string with a readability analysis of the program.
The analysis will be to calculate how many words in the average sentences composed. For example, the following text string,
"An example. A sentence ends with a period. Paragraph and end."
consists of three sentences and ten words. Average number of words per sentence is 10/3 = 3.333333.
The more words, on average sentences consist of, the more difficult to read the text usually considered.
Assume that before each word is always a kind of character, '', except for the text string first word. Assume that all sentences end with the dot character, '.'. You do not take into account any other whitespace, punctuation, abbreviations and other things that can complicate the analysis.
Describe your steps in the Top Down Design in your documents, at least two steps to be reported. The reported solution should be consistent with the application you have built. Present also project folder for the developed program.
