Code
Code, which can be short for "source code", is a term used to describe text that is written using the protocol of a particular programming language, such as C, Java, Perl, PHP, or others. Code can also be used in a less formal fashion to refer to text written for markup or styling languages like HTML and Cascading Style Sheets (CSS). For example, you may see people make reference to code in numerous languages, such as "C code", "PHP code", "HTML code", or "CSS code".
