Storage class determins the life time of the storage of an
identifier.
where the identifier is stored is determined by storage
class
Identifier means name given to a variable or a function.
There are 2 storage classes
1.Automatic storage class
2.static storage class
Automatic storage class
-----------------------
Variables declared within a function body are called
automatic variables.Auto is the keyword used to declare
automatic variables. By default and without the use of auto
keyword, the vaeiables inside the function are automatic
variables.auto matic variables are stored in stack.
Variables declared as register are also automatic they
are stored in fast registers of CPU.If sufficient number of
registers are not available, the register variables also
stored in stack.
When the function is calling these variables are
allocating memmory automatically. When the function is
finished and exits, the controll trnsfered to the calling
program the memory allocated will be destroyed.
2.Static storage class

Sir,please help me out with the code of this question. Write an interactive C program that will encode or decode multiple lines of text. Store the encoded text within a data file, so that it can be retrieved and decoded at any time. The program should include the following features: (a) Enter text from the keyboard, encode the text and store the encoded text in a data file. (b) Retrieve the encoded text and display it in its encoded form. (c) Retrieve the encoded text, decode it and then display the decoded text. (d) End the computation. Test the program using several lines of text of your choice.

The purpose of this exercise is to benchmark file writing and reading speed. This exercise is divided into two parts. a). Write a file character by character such that the total file size becomes approximately >10K. After writing close the file handler, open a new stream and read the file character by character. Record both times. Execute this exercise at least 4 times b). Create a buffer capable of storing 100 characters. Now after generating the characters, first store them in the buffer. Once the buffer is filled up, store all the elements in the file. Repeat the process until the total file size becomes approximately >10K.While reading read a while line, store it in buffer and once buffer gets filled up, display the whole buffer. Repeat the exercise at least 4 times with different size of buffer (50, 100, 150 …). Records the times. c). Do an analysis of the differences in times and submit it in class.
