If you can do without using std::string at all then the following is simpler and will be faster. And you can use Inline C (though it works as is with Inline CPP):
int countGC(char * gcString) {
int res = 0;
for (int i = strlen(gcString); i-->0; gcString++) { if (*gcStr
+ing == 'C' || *gcString == 'G') { res++; } }
return res;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
