Programming C# (Visual Studio Version 2008)

Q1. Write a GUI program that reads a five-letter word from the user and produces all possible three letter combinations that can be derived from the letters of the five-letter word. For example, the three-letter words produced from the word "bathe" include the commonly used words "ate," "bat," "bet," "tab," "hat," "the" and "tea," and the 3-letter combinations "bth," "eab," etc. Have a "Save" button and use SaveFileDialog to save the results to a file. Also, have an "Open" button and find the five letters which are used to create the opened file. A possible GUI is given below; feel free to design your own GUI.

Q2. Suppose we wish to process survey results that are stored in a file. First, create a Windows Form that prompts the user for survey responses and outputs each response to a file. Use StreamWriter to create a file called numbers.txt. Each integer should be written using method Write.

Then add a TextBox that will output the frequency of survey responses. You should read the survey responses from numbers.txt. The responses should be read from the file by using a StreamReader. Class string's split method should be used to split the input string into separate responses, then each response should be converted to an integer. The program should continue to read responses until it reaches the end of file. The results should be output to the TextBox.

A possible GUI is given below; feel free to design your own GUI.
