2.1 pseudocode and Flow Charts

1. psuedo code

   • number1=input()
     • number2=input()
       • if number 1>number 2 then
         • print ("the largest number is" + number1)
           • else
             • print ("the largest number is" + number 2
               • end

2. global commands show variable can be used sub routines

3. CONST=constant variable in the programme that wont change

   • iteration : while....=x
     • (condition) endwhile
       • iteration : for … 0 to 5:
         • (count) next

4. flow chart -

   • terminators, arrows, yes/no,input/output, decision, sub routine

5. != (not equal to) ==(equal to)

   • <,<= (less than (or equal to))
     • >,>= (more than (or equal to))
       • MOD (6/2=3(no remainder)) shows the remainder ie 7/2=3 r1
         • DIV integer division (7 DIV 2=3) whole number

6. selection

   • if x ==6 THEN
     • ELSEIF
       • ELSE
         • SWITCH X:
           • CASE "a":
             • CASE "b":
               • DEFAULT
                 • ENDSWITCH
