NAME

6       libcvc4 - a library interface for the CVC4 theorem prover
7

SYNOPSIS

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

DESCRIPTION

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.
