1.2.4 types of programming language

Question 1

what are programming paradigms?

Answer 1

different approaches to using a programming language to solve a problem

Question 2

which 2 broad categories are programming paradigms split into?

Answer 2

imperative, declarative

Question 3

state the advantages of procedural programming

Answer 3

can be applied to a wide range of problems, relatively easy to write and interpret

Question 4

state a use of declarative programming

Answer 4

expert systems, artificial intelligence

Question 5

identify the 4 main structures used in structured programming

Answer 5

sequence, selection, iteration, recursion

Question 6

how does assembly language different from machine code?

Answer 6

assembly language uses mnemonics rather than binary, one line in assembly language is equal to one line in machine code

Question 7

What is the function of the STA mnemonic?

Answer 7

storing the value in the accumulator at the given memory address

Question 8

what is the function of the BRP mnemonic?

Answer 8

branches to a given address if the value in the accumulator is positive, it is a conditional branch

Question 9

state the function of the opcode and operand

Answer 9

the opcode specifies the instructions to be performed and the addressing mode. the operand holds a value which is related to the data on which the instruction is to be performed

Question 10

state the 4 addressing modes

Answer 10

immediate addressing, direct addressing, indirect addressing, indexed addressing

Question 11

what is a class?

Answer 11

a template for an object that defines the state and behaviour of an object is an instance of a class

Question 12

give one disadvantage of object oriented languages

Answer 12

requires a different style of thinking which can be difficult for programmers accustomed to other paradigms to pick up, OOP may not be suited to all types if programs, generally unsuitable for smaller problems
