More while Loops:

In this lab, you will get more practice using while Loops.

Example Program:

EOF$-$controlled while loops are a special case of flag$-$controlled while loops. When we are reading from a

file and the end of the file is reached, a special case flag is set to true. For StreamReader, this is

EndOfStream.

The example program for EOF$-$controlled while loops reads a series of numbers from an input file and

finds the average of those numbers. Download EOF$\_$Average.cs and create a project for it in Visual C#$.$

Read and understand the code and run the program.

Your Program:

For your program you will search a dictionary file for the word provided by the user. First ask the user to input a word. Search the dictionary file for that word and tell the user whether or not the word was

found. This program demonstrates a linear search technique. When you perform a linear search, you start at the beginning of a list and search through the list in order until you reach the desired item or the end of the list. You may need to make use of a break statement to exit the loop early if you find a match. Linear

search is a very inefficient method, and we will learn about better search techniques later. Here is a dictionary file for Windows that you can use. You must either put your dictionary file in your

Visual C# project folder, or specify the path to the dictionary file in your program. Your output should look similar to the following figure. Turn in your completed program.

Challenge:

For the challenge component this week, modify your program through the use of the toLower$()$ string

function so that capital or lowercase spelling by the user doesn$$t affect the program. $$Hello$$ or $$hello$$

should both return a positive answer $($in the normal program, $$Hello$$ will not, because the capital $$H$$

won$$t match$).$

Additionally, rewrite the program to make use of a do$...$while loop, instead of a while loop. Submit both

forms $($while for the basic lab, and do$...$while for the challenge$).$

If you can be specific on the c# code and detailed with linear search. If you can also be detailed on how to attach txt file so the program opens the file. If the code can show the sample output.

Sample Output:

Please enter a word; hells

That is a real mord?!
