12th Class Computer Science Chapter 14 Short Questions with Answers Online Preparation

Question # 1

Describe the purpose of file handling .

Ans 1: File Handling: A file represents a sequence of bytes on the disk where a group of related data is stored. File is created for permanent storage of data. It is a readymade structure.
In C Language, we use a structure pointer of file type to declare a file.
File *fp
Types of function: C provides a number of functions that helps to perform basic file operations.

Question # 2

Name two type of stream used in files.

Ans 1: Name of Stream: There are two types of stream:
- Text Stream
- Binary Stream

Question # 3

What is text file?

Ans 1: A text file is a name collection of characters saved in secondary storage e.g on a disk. A text file has not fixed size.To mark the end of text file, a special end-of-file character is placed after the last character in the file (denoted by EOF in C.) When we create a text file using a text editor such as notepad, pressing the ENTER key causes a newline character (denoted by \n in C )to be placed at the end of each line, and an EOF marker is placed at the end of the file.

Question # 4

What is binary system?

Ans 1: A binary system is a sequence of bytes with a one-to-one correspondence to those on the external device (I.e.,no translation occur). The number of bytes written or read is the same as the number on the external device.However, an implementation-defined number of bytes may be appended to a binary stream

Question # 5

Define Stream.

Ans 1: Stream: Avery important concept in C is the stream . A stream is a logical interface to a file. A stream is associated to a file using an open operation. Astream is disassociated from a file using a close operation.
Types:There are two types of stream:
- Text Stream
- Binary Stream
Ans 2:

Question # 6

What do you mean by text stream?

Ans 1: A text steam is a sequence of character . In a text stream, certain character translation may occur(e.g., a newline may be converted to a carriage return\line-feed pair). This means that there may not be one-to-one relationship between the characters written and those in the external device.

Question # 7

Why is it important to close a file?

Ans 1: When a program has no further use of file, it should close it with fclose(V ) library function.
Syntax:
int fclose (FILE* fp)

Question # 8

What is File Pointer ?

Ans 1: A file pointer is a variable of type FILE that is defined in stdio.h. To obtain a file pointer variable, a statement like the following is used: FILE* fp;
Explanation :
We Know the symbol '*' as the arithmetic multiplication operator. But it has entirely different meaning when used with a data type such as int, double ,or FILE. It represents a pointer to the variable of type with which it is used e.gint* represents a pointer to an integer , float represents a pointer to afloat variable , and FILE * represents a pointer to a variable of type FILE. Conceptually, a pointer is a memory cell whose content is the address of another memory cell.

Question # 9

Compare Binary and Text Stream.

Ans 1: Binary Stream:
- As Binary stream is a sequence of bytes.
- Translations do not occur.
- One-to-one relation is present
Ans 2: Text Stream:
- A text stream is a sequence of characters.
- Translations may occur.
- One-to-one relation is not present.

Question # 10

Define pointer.

Ans 1: A pointer is a memory cell whose content is the address of another memory cell.
