[CP:AMA] 4 Expressions

"One of C's distinguishing characteristics is its emphasis on expressions-" Mmm... distinguishing from what? Let's take a tiny survey.

• Fortran: sure. Fortran has expressions in its language specification, but its emphasis is on statements.
  

So one can say `for those days that C had been developed C's emphasis on expressions, C's emphasis on expressions is its distinguishing characteristics, except for Lisp'.

• 4.2 Assignment Operators
  The explanation for side effects is great. I finally understand why the assignment in C is thought to have side effects; because it is an operator or isn't an statement.

• 4.4 Expression Evaluation

• 4.5 Expression Statements
  `Expression Statements' is somewhat weird term, but its meaning is clear.
  "C has the unusual rule that any expression can be used as a statement."
