9 A small program like:
10
11 #include <iostream>
12 #include "expr/expr_manager.h"
13 #include "smt/smt_engine.h"
14
15 using namespace CVC4;
16
17 int main() {
18 ExprManager em;
19 SmtEngine smt(&em);
20 Expr onePlusTwo = em.mkExpr(kind::PLUS,
21 em.mkConst(Rational(1)),
22 em.mkConst(Rational(2)));
23 std::cout << language::SetLanguage(language::output::LANG_CVC4)
24 << smt.getInfo("name")
25 << " says that 1 + 2 = "
26 << smt.simplify(onePlusTwo)
27 << std::endl;
28
29 return 0;
30 }
31
32 gives the output:
33
34 "cvc4" says that 1 + 2 = 3

38 The main classes of interest in CVC4's API are ExprManager, SmtEngine,
39 and a few related ones like Expr and Type.
40
41 The ExprManager is used to build up expressions and types, and the
42 SmtEngine is used primarily to make assertions, check satisfiabil‐
43 ity/validity, and extract models and proofs.

50 design and internals of CVC4. It is maintained at
