PL

Question 1

primitive, composite data types

Answer 1

primitive: basic data types (int, float, boolean)
building blocks
directly stores values in memory

composite: (array, class, interface)
structures to build with
can store multiple values

Question 2

integer types

Answer 2

signed: positive, negative, zero
more positive and negative values
int8..64

unsigned: only non-negative whole numbers
more positive values
uint8..64

memory usage: 8..64 bits
operations: basic arithmetic operations

Question 3

enumeration types

Answer 3

enumeration types: usage, definition, implementation, benefits.

Question 4

common derived types

Answer 4

common derived types: arrays, pointers, classes and structures.

Question 5

compiler

Answer 5

compiler:
source,
front end(syntax analyzer, semantics analyzer),
intermediate code generator,
back end(mach ind optimizer, code generator, mach dep optimizer),
machine code.

Question 6

loader

Answer 6

loader: loading, preparing and execution for files.
source program,
translator,
object modules,
linker,
binary program,
(loader, data)
binary program,
result.

Question 7

implementation methods

Answer 7

implementation methods:
execution,
compilation,
interpretation,
hybrid.

Question 8

code execution

Answer 8

code execution:
source code,
compiler,
object node, library,
linker,
executable program.

Question 9

compiler architecture

Answer 9

compiler architecture:
source program,
lexical analyzer,
syntax analyzer,
semantics analyzer,
intermediate code generator,
code optimizer,
code generator,
target program.

Question 10

front end vs back end

Answer 10

front end: checks if the program written correctly
back end: translation into assembly.

Question 11

advantages of compiling:

Answer 11

advantages of compiling:
free from lexical errors,
free from syntax errors,
free from semantics errors,
even complex programs are fast,
risks reduced.

Question 12

composite data types

Answer 12

composite data types: complex data structure.
character string, pointers, user defined data types, files.

Question 13

structured data types

Answer 13

structured data types: create new data types and operations.
records, arrays, lists, sets.
