<h3>Testing Your Interpreter, Part 1</h3>

<p>Test 1: This code should return 150.
<pre>
return 150;
</pre></p>

<p>Test 2: This code should return -4.
<pre>
return 6 * (8 + (5 % 3)) / 11 - 9;
</pre>
</p>

<p>Test 3: This code should return 10.
<pre>
var z;
z = 10;
return z;
</pre></p>

<p>Test 4: This code should return 16.
<pre>
var x = (5 * 7 - 3) / 2;
return x;
</pre></p>

<p>Test 5: This code should return 220.
<pre>
var x = 10;
var y = 12 + x;
return x * y;
</pre></p>

<p>Test 6: This code should return 5.
<pre>
var x = 5;
var y = 6;
var m;
if (x <= y)
  m = x;
else
  m = y;
return m;
</pre></p>

<p>Test 7: This code should return 6.
<pre>
var x = 5;
var y = 6;
var m;
if (x >= y)
  m = x;
else
  m = y;
return m;
</pre>
</p>

<p>Test 8: This code should return 10.
<pre>
var x = 5;
var y = 6;
if (x != y)
  x = 10;

</pre></p>

<p>Test 9: This code should return 5.
<pre>

return x;
</pre></p>

<p>Test 10: This code should return -39.
<pre>
return 6 * -(4 * 2) + 9;
</pre></p>

<p>Test 11: This code should give an error (using before declaring).
<pre>
var x = 1;

</pre>
</p>

<p>Test 12: This code should give an error (using before declaring).
<pre>

</pre></p>

<p>Test 13: This code should give an error (using before assigning).
<pre>
var x;
var y;
x = x + y;
return x;
</pre></p>

<p>Test 14: This code should give an error (redefining).  This is not a required error, but it would be nice if you
could catch these.
<pre>
var x = 10;
var y = 20;
var x = x + y;
return x;
</pre></p>


<p>Test 15: This code should return true (not #t).
