Variables and constants must be declared to be some data type. String - may use double or single quotes and may contain special characters. There is no THEN and the ELSE is optional. Example of if-else. The break statement is normally used to exit a loop or a case in a switch statement.
Execution resumes at the first statement following the end of the loop or case.
The continue statement immediately forces the next iteration of a loop. I.e. it causes execution to resume at the top of the loop. Use this as if it were a variable pointing to the current object. Functions headers must be defined before the function is called. Arrays begin with index 0.
