This document discusses different types of files in C programming. It covers text vs binary files, sequential vs random access files, and different file handling functions like fopen(), fclose(), fwrite(), and getc()/putc(). It also describes the modes used for opening files, differences between text and binary modes, advantages of sequential files like lower storage and faster access, and advantages of random files like flexible data access and better performance for large databases.

1. Text vs
binary files
And
Sequential files
vs random files
With
modes

2. 1. File handling
fopen() :- Create a new file or open a exiting file .
Functi
ons
fclose() :- Close a file .
fwrite() :- To write a file .
get c () :- Read a character from a file .
put c () :- Write a character to a file .

3. Syntax
 fp=fopen(“file name .text”, mode”);
int fclose(FILE *stream);
int getc(FILE *stream);
int putc(int character, FILE *stream);

4. Text and binary modes of
files
Reading from a file
Writing to a file
Appending to a file
Reading binary data from a file

5. Sequential and
Random files
Sequential access means that a group of element is accessed predetermined
ordered sequence .
Sequential files
Random files
Random access files will be spitted into pieces and will be stored wherever
space available .

6. Advantages of
sequential files
 Lower storage requirement .
 Simple file management .
 Logging and auditing .
 Data streaming .
 Limited storage environment .
 Faster data access .

7. Advantages of
random files
Flexible data access .
Easier data management .
Better performance .
Large databases .
Scientific data analysis .
