Hashing search: key & value

*When sorted, Binary search

*When not sorted, Liner search

 
 

Binary Tree search: Tree structure

File

When you use file, if same statement write one by one, it is not efficient.

Because it has to connect other location file many times. So we use Buffer.

 
 

FileStream fs = new Filestream();

(

"xyz.txt",

FileMode.Create,

FileAccess.Write,

FileShare.Read

);

 
 

'\' is escape sequence, so we have to use '\\' or '@'.

'@' is easier than '\\', because if you use '@', it allows you to use '\'whole sentence.
