Features
Sequence- A sequence means that the instructions that are in an Alger rhythm are in a specific order. Its very important that the instructions are in order because the Alger rhythm will not work correctly.


Selection- Is needed where one or more options are available and its actual a decision or question because this decision will need two different paths to the program. If we do not select what we want the program to do the solutions it will create will not be realistic. To be able to do selections in programming we need to use IF and Else statements for example if we say : Ask which college you go then the following step is the selection is "if going to north notts college", you say (its amazing) then the third step is using else and we might say  (its a stupid decision)


Until-


while- it will execute only when the statement is true


Do-


Variables


naming and convention-


local and global variables- Is when it is outside of a function and you can access and modify it throughout your program and local is inside of a function definition


local operators- This operator can make a program to make a decision based on multiple statements every operand is a condition and it has to be evaluated to a true or false value and then those values are used to determine the overall value of the operator one and operator two.
