Printing a cross across another symbol

Is there any command or macro for printing a character with a cross over it?

Are you referring to something like cancelling? As in How to strike through obliquely, e.g. to indicate cancellation? –  Werner Sep 3 at 13:12
I need a double stroke, like a big X across a C. –  user56153 Sep 3 at 13:14

With tikz anything is possible if you are determined.

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes}

\newcommand*{\mycancel}[2][draw]{%
\begin{tikzpicture}
\node[cross out,inner sep=0.5pt,outer sep=0pt,#1]{#2};
\end{tikzpicture}
}

\begin{document}
\mycancel[draw=red]{C} \mycancel{$\alpha$}
\end{document}


But there is already a package for it and you can use it in math mode.

\documentclass{article}

\usepackage{cancel,color,amsmath}

\begin{document}
$\xcancel{C}$

\renewcommand{\CancelColor}{\color{red}}
$\xcancel{C}$

$\xcancel{\text{C}}$

\end{document}
