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

Question # 1

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 # 2

What are programming Languages?

Ans 1: Programming Languages : The language which are used to write computer programs are called Programming language.
Categories : There are two broad categories of programming languages
1. Low Level Languages
2. High Level Languages

Question # 3

Define Source Code.

Ans 1: Source code is a set of instructions and statements written by a programmer using a computer programming language. This code is later translated into machine language. By a compiler. The translated code is referred to as object code.

Question # 4

Define the term Debug.

Ans 1: Debugging is the routine process of locating and removing program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications.

Question # 5

Differentiate between Compiler and Interpreter.

Ans 1: Compiler : Compiler translate the source program into an object program with .obj extension . A Compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer processor uses.
Ans 2: Interoperate : An Interpreter is a computer program that directly executes I.e performs, instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program.

Question # 6

What is Syntax ?

Ans 1: Syntax Errors : A Syntax error occurs when the program violates one or more grammar rule of C language.
The compiler detects these errors as it attempts to translate the program. If a C statement has syntax error, it cannot be translated and the program could not be executed.
Causes : There can be many causes of syntax errors:
1. Missing terminator I.e the semicolon using a variable without declaration , missing any of the delimiters I.e, {or}etc
2. A syntax error may also occur when an invalid equation is entered into a calculator.

Question # 7

Why Source code cannot be executed directly?

Ans 1: Source code is a human readable but cannot be executed directly . To execute the program, hower the programmer must translate it into machine language ,the language that the computer understands. The first step of this translation process is usually performed by a utility called a compiler .

Question # 8

Define Delimiters?

Ans 1: Delimiters : Next to the function definition are braces, which indicate the beginning and end of the function body. These braces are called delimiters. The opening braces {indicates the beginning of a block of code (set statement) .while the closing brace) represents the end of a block of code.

Question # 9

How program logic is implemented in un-structured programming languages?

Ans 1: In un-structured programming languages, the entire logic of the program is implemented in a single module (function), which cause the program error prone, difficult ti understand, modify and debug.

Question # 10

Define Bug?

Ans 1: Bug : The programmer may come across errors while writing a computer program. In programming languages, theses errors are called 'Bugs" and the process of finding and removing bugs is called debugging
There are three types of bugs/Errors.
1. Syntax Error
2. RunTime Error
3. Logical Error
