An expression consists of constants, variables, and operators. An expression
followed by a return or a semicolon is a simple statement. A sequence of simple
statements would be executed one by one by the interpreter. Sometimes we want
some statements to be executed repeatedly, or we want some statements to be
executed only when certain conditions are met. To achieve this we need the flow control
structures which specify the order of execution of statements.
