CExpression

CExpression[arg]
is a symbolic representation of code that will format using CForm[arg].
  • SymbolicC expressions are inert; they evaluate to themselves, staying in an unevaluated form.
  • SymbolicC expressions can be converted into a C string with ToCCodeString.
To use SymbolicC you first need to load the package:
Here the result is generated by CForm:
You can prevent evaluation by using HoldForm:
You can include a semicolon by inserting the arguments into a list:
