- 1IntergerA whole number.
- 2Floating pointA number with a decimal point. Sometimes called a real number.
- 3CharacterA single, number or symbol.
- 4StringA series of characters that can include letters spaces and whole numbers.
- 5BooleanCan only have one of two values , either true or false.
- 6VariableA memory location that can be changed while the programme is running.
- 7ConstantA memory location that can not be changed while the programme is running.
- 8Differences between variables and constantsA variable can be changed while the programme is running but a constant can not be changed.
- 9AdditionAdds two values together.
- 10SubtractionTakes the second value away from the first value.
- 11MultiplicationMultiplies two values together together.
- 12Real divisionIt divides the first value
by the second value. - 13NOT.
- 14Integer DivisionUsed to find the quotient
(integer number before
the decimal point) after division. - 15Remainder(MOD)Used to find the remainder (modulus) after division.
- 16Exponential(DIV)Raises the value to the
power of the exponent - 17>Greater than.
- 18>=Greater than
or equal to. - 19<Less than.
- 20<=Less than or equal to.
- 21==Equal to.
- 22!=Not equal too.
- 23ANDBoth inputs need to be True
for the result to be True. - 24ORIf either or both of the inputs are True then the result will be True.
- 25IterationIteration is the process of repeating a set of instructions for a fixed number of time until a condition is met.
- 26SelectionSelection is when ana algorithm has to choose two or more options.
- 27SequenceSequence is a series of instructions in which each instruction i executed after the previous one has been exulted.
- 28Data typesData types are presented in strings of 1s and 0s. Computer must be aware of the data type values stored in variables so that data is interpreted and manipulated correctly.
- 29CastingCasting is used convert one data type into another e.g. int(stringVariable) would convert into a string integer.
- 30Concatenationis the joining of strings.
