In pseudocode you use similar terms to flowcharts however you have to lay it out in a different way with all of the outputs and inputs being shown. All instructions must be written in capital letters. The instructions include:OUTPUT = The device outputs a piece of data (question e.t.c) INPUT = The user puts something into the programSTORE = Allows the device to remember a variableIF = A question checking a condition, like a decision in flowchartsTHEN = Showing what to do if the answer to IF is true (yes)ELSE = Showing what to do if the answer to IF is false (no)REPEAT UNTIL = Repeating the algorithm until a condition is metThe most common way to start an algorithm is with a question written like this:OUTPUTINPUTSTOREThis allows the question to be asked, an answer to be revived, and the answer to be stored for later use as a variable. It would look like this in a practical situation.OUTPUT: "What is your name?"INPUT: user inputs nameSTORE: user answer in name variableAfter this it would be common to add an IF, THEN, ELSE sequence afterwards to determine what happens next. For example:IF name (this is the variable) = "Oliver" THEN OUTPUT: "That's mine too!"ELSE OUTPUT: "Nice name, mine's Oliver"With pseudocode you would never write in the start and stop like you do with flowcharts.Useful BBC Bitsize: http://www.bbc.co.uk/education/guides/z3bq7ty/revision/2
