a post with code

This theme implements a built-in Jekyll feature, the use of Rouge, for syntax highlighting. It supports more than 100 languages. This example is in C++. All you have to do is wrap your code in a liquid tag:

{% highlight c++ linenos %}
code code code
{% endhighlight %}

The keyword linenos triggers display of line numbers. Produces something like this:

1
2
3
4
5

int main(int argc, char const \*argv[])
{
    string myString;

    cout << "input a string: ";
    getline(cin, myString);
    int length = myString.length();

    char charArray = new char * [length];

    charArray = myString;
    for(int i = 0; i < length; ++i){
        cout << charArray[i] << " ";
    }

    return 0;
