CINT is a command line C/C++ interpreter that is included in the object oriented histogramming package ROOT. Although intended for use with the other faculties of ROOT, CINT can also be used as a standalone addition to another program that requires such an interpreter.
CINT is an interpreted version of C or C++, much in the way BeanShell is an interpreted version of Java. In addition to being a language interpreter, it offers certain bash-like shell features such as history and tab-completion. To accomplish the latter, it relies heavily on the reflection support built into ROOT. User classes that follow these interfaces may also take advantage of these features.
The language interpreted by CINT is actually somewhat of a hybrid between C and C++, covering about 95% of ANSI C and 85% of C++. The syntax, however, is a bit more forgiving than either language. For example, the operator
-> can be replaced by
. with only an optional warning. In addition, statements on the command line do not need not end with a semi-colon, although this is necessary for statements in macros.
A very useful feature of CINT is that instances of classes that derive from
TNamed, which includes all of the standard classes of ROOT, can be accessed by their name rather than a variable.
