Math & Science ⇒ brackets problem

[shoshia]

Hello all
I'm trying to make small CPP tutorial and try to show function type, name, arguments and body:
First code

Code: Select all

\begin{eqnarray*} 
\begin{aligned}
\overbrace{int}^{\text{TYpe}}  \overbrace{sqequation}^{\text{Name}} &
 \overbrace{(const\  double\& \ a, const\  double\& \ a,const\  double\&\  a)}^{\text{Parameters}} \\
\end{aligned}
\\
\left.
\begin{aligned}
\{& \\
&\boxed {\phantom{a+b}}\\
&\boxed {\substack{\text{program} \\ \text{code}}   } \\
&\boxed {\phantom{a+b}}\\
\}& \\
\end{aligned} \right\}\quad\text{ Body}
\end{eqnarray*}

second code

Code: Select all

\begin{eqnarray*} 
\left.
\begin{aligned}
\overbrace{int}^{\text{ტიპი}}  \overbrace{sqequation}^{\text{name}} &
 \overbrace{(const\  double\& \ a, const\  double\& \ a,const\  double\&\  a)}^{\text{Parameters}} \\
\{& \\
&\boxed {\phantom{a+b}}\\
&\boxed {\substack{\text{Program} \\ \text{code}}   } \\
&\boxed {\phantom{a+b}}\\
\}& \\
\end{aligned} \right\}\quad \text{ Body}
\end{eqnarray*}

Problems:
with one code \right} is "too high"--it must be below function.
with another one function body is shifted .
any ideas?
maybe matrix approach can give right solution?

First of all read a paper about the reasons why not to use the eqnarray environment [1]. Afterwards start using the align environment from the amsmath package and try again to align the math expression.
