<span id="programs-and-blocks"></span><h2>Programs and Blocks<a class="headerlink" href="#programs-and-blocks" title="Permalink to this headline"></a></h2>
<p>The basic structure of a PaddlePaddle program is some nested blocks, as a C++ or Java program.</p>
<ul class="simple">
<li>program: some nested blocks</li>
<li><a class="reference internal" href="block.html"><span class="doc">block</span></a>:<ul>
<li>some local variable definitions, and</li>
<li>a sequence of operators</li>
</ul>
</li>
</ul>
<p>The concept of block comes from usual programs.  For example, the following C++ program has three blocks:</p>
<div class="highlight-c++"><div class="highlight"><pre><span></span><span class="kt">int</span> <span class="nf">main</span><span class="p">()</span> <span class="p">{</span> <span class="c1">// block 0</span>
