Kinds of statements

Most basic
  assignment statement
  // <lval> = <expression>; //
    where lval denotes some expression that names memory, such as
    a variable name or an array entry reference.
  // A[3] = A[2} + x/13 ; //
    expressions - issue of parenthesization and its convenient, partial,
    optional elimination by taking advantage of operator precedence.

  return statement
  // return <expression>; //

Sequence
  block statement
  // { <statement> <statement> ... } // 
  Note lack of ending semicolon.

Choice
  if statement
  // if ( <boolean expression> )
       <statement-to-be-executed-if-true>
     else
       <statement-to-be-executed-if-false>
     //
  The else part is optional
	
  switch statement
  // ... //
  Not often needed.  Look into this later. 

Repetition
  while statement
  // while ( <boolean expression> ) <statement> //
  do-while statement
  // do <statement> while ( <boolean expression> ) //
  for statement
  // for ( <initialization> <boolean condition>; <incrementation> )
       <statement> //
  The body of these loop constructs (the <statement> part) is 
  usually a block statement.

  The for statement is equivalent to 
  { <initialization>
    while ( <boolean condition> ) 
      { 
      <statement> 
      <incrementation> 
      }
  }

  the do-while is equivalent to
  {  <statement>
     while ( <boolean expression> )
       <statement>
  }
