Camel case & Pascal Case

CamelCase (camel case or camel-case)—also known as medial capitals—is the practice of writing compound words or phrases in which the elements are joined without spaces, with each element's initial letter capitalized within the compound and the first letter is either upper or lower case—as in "LaBelle", BackColor, "McDonald's" or "iPod". The name comes from the uppercase "bumps" in the middle of the compound word, suggestive of the humps of a camel. The practice is known by many other names. In computer programming, it is called Pascal case if the first letter is capitalized, and camel case otherwise
