Syntax Highlighting

GFM syntax highlighting is also available by using fenced code tags with a label denoting the language, as such:

```c++
#include <stdio>

int main() {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}
```

which results in:

#include <stdio>

int main() {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

To denote the language you can either use one the language’s extensions as the label, or the full name of the language (which is not case-sensitive).
