12th Class Computer Science Chapter 8 Short Questions with Answers Online Preparation

Question # 1

Why is Function used in program?

Ans 1: Function Main : Every C program has a main function. In fact, main is the function where the execution of the C program begins . The rest of lines of program forms the body of the main function , the body is enclosed in braces {and}.
Main Function Definition :
Syntax : Void main (void)
{body of main function
}

Question # 2

Define High Level Language ?

Ans 1: Program languages whose instructions resemble the English Language are called high-level languages. Every high-level language define a set of rule of writing. Programs called syntax of the language. Every instruction in the high-level language must confirm to its syntax.

Question # 3

What is compiler?

Ans 1: Compiler translates the source program into an object program with .obj extension .

Question # 4

What is statement terminator?

Ans 1: Statement Terminator : Every statement in a C program terminates with a semicolon (;).If any of the statement is missing the statement terminator, the compiler will report it the following error message. Statement missing:

Question # 5

What is the difference between machine language and assembly language ?

Ans 1: Machine Language :Machine language is the native language of the computer. The computer does not need any translator to understand this language. Programs written in any other language must be converted to machine language so that the computer can understand them. Every machine language instruction consists of string of binary 0s and 1s.
Ans 2: Assembly Language :Assembly level language is a set of codes that can run directly on the computer's processor. This type of language is most appropriate in writing operating systems and maintaining desktop applications. With the assembly level language it is easier for a programmer to define commands. It is easier to understand and use as compared to machine language.

Question # 6

Name two main categories of Programming Languages.

Ans 1: There are two broad categories of programming languages
1. Low Level Languages
2. High Level Languages

Question # 7

What are preprocessor directives?

Ans 1: Preprocessor directives are commands that give instruction to the C preprocessor. The preprocessor is a program that modifies the program .(Source program) prior to its compilation. A preprocessor directive always begins with the symbole (#). In the above program, include is preprocessor directives.

Question # 8

State the purpose of header file.

Ans 1: The C and C++ standard library contains files containing the standard functions that are known as header files. Header file provide function prototypes, definition for library functions .
Data types and contants used with the library functions are also used in them .

Question # 9

Described the concept of linker .

Ans 1: The Linker is a program the combine the object program with additional object files that may be needed for the program to execute and save the final machine language program as an executable file on disk. In Turbo C++ , the linker can be invoked by selecting Complile | Link from the menu bar. The linker combine different library files to the object file and produces an executable file with extension

Question # 10

Write the use of Turbo C ++.

Ans 1: Use of Turbo C++ : Turbo C++ is a Borland International's Implementation of a compiler for C language . In addition to a compiler' TC provides a complete IDE to create, edit and save programs is called TC editor . It is also provides a powerful debugger that helps in detecting and removing errors in the program. It is very easy to write C programs in its editor.
