Delayed evaluation solves this problem, and can be implemented in C++ by letting operator+ return an object of an auxiliary type, say VecSum, that represents the unevaluated sum of two Vecs, or a vector with a VecSum, etc. Larger expressions then effectively build expression trees that are evaluated only when assigned to an actual Vec variable ...
A class template is instantiated by passing a given set of types to it as template arguments. [5] The C++ Standard Library contains many class templates, in particular the containers adapted from the Standard Template Library, such as vector.
The template can be repeatedly nested 6 or 7 levels, one inside the other, because the outer-most is completed before running either the then/else inner levels. This template can be substituted, when the expression or comparison will not change. Functionally, a lead-space character is stored, internally, as a simple blank character.
The entire "instead of" clause will not appear if this is blank (i.e., the template will end with the wording of |error= or its default value). |section= (optional) By default, this display "article" in an article and "page" on all other pages.

The Matrix Template Library (MTL) is a linear algebra library for C++ programs. The MTL uses template programming , which considerably reduces the code length. All matrices and vectors are available in all classical numerical formats: float , double , complex<float> or complex<double> .
This is the template test cases page for the sandbox of Template:Contains special characters to update the examples. If there are many examples of a complicated template, later ones may break due to limits in MediaWiki; see the HTML comment "NewPP limit report" in the rendered page.
Note on special characters: if the value to be highlighted contains an equal sign, it must be escaped: use {{=}} instead of a bare equal sign character. Examples [ edit ] {{param value|2blanks between}} yields: 2blanks between
