For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
Access to and manipulation of multiple DOM nodes in jQuery typically begins with calling the $ function with a CSS selector string. This returns a jQuery object referencing all the matching elements in the HTML page. $("div.test"), for example, returns a jQuery object with all the div elements that have the class test. This node set can be ...
The Math object contains various math-related constants (for example, π) and functions (for example, cosine). (Note that the Math object has no constructor, unlike Array or Date. All its methods are "static", that is "class" methods.) All the trigonometric functions use angles expressed in radians, not degrees or grads.
// each minterm is of the form "1001", "1010", etc and can be represented with a string. function getPrimeImplicants(list minterms) is primeImplicants ← empty list merges ← new boolean array of length equal to the number of minterms, each set to false numberOfmerges ← 0 mergedMinterm, minterm1, minterm2 ← empty strings for i = 0 to ...
A string is considered true if it contains at least one non-whitespace character (thus, for example, the #if function interprets the strings "0" and "FALSE" as true values, not false). Any string containing only whitespace or no characters at all will be treated as false (thus #if interprets " " and "", as well as undefined parameters, as false ...
