Compiler - Intro

Language Processor helps in translating

• intermediate code to machine executable code

• high level code to intermediate code

• low level code to intermediate code

• high level code to machine executable code

Both assembly language and machine language are categories under low level languages.

• Yes

• No

choose the correct order in which the language processor works. Pre processor,Compiler,Assembler,Linker

• 1,3,4,2

• 1,2,3,4

• 1,2,4,3

• 1,4,3,2

Name two main phases of the compiler

(a)  

Choose the correct answer for blank space in correct order.

• semantic, syntax, lexical

• syntax, linear, semantic

• linear, semantic, syntax

• lexical, syntax, semantic

For position := initial + rate * 60 fill the intermediate code

temp1 = inttoreal(60)

temp2 = id3 * temp1

-------------------------

id1 = temp3

(a)  

In lexical analysis phase, input - token and output - lexeme

• yes

• no

Identify the token from the given options.

• if

• >=

• identifier

• white space

Identify the lexeme from the given options.

• <=

• literal

• identifier

• num

_________ is a process of finding a parse tree for a string of tokens.

• Parsing

• Tokenizing
