This template implements a for loop or a foreach loop. This template calls a user-specified template (the "called template") multiple times: once for each value in either 1) an iterated sequence or 2) an explicit list. Each value in the sequence or list is passed to the same specified parameter of the called template (the "variable parameter").
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement . Unlike other for loop constructs, however, foreach loops [ 1 ] usually maintain no explicit counter: they essentially say "do this to everything in this ...
The else clause in the above example is linked to the for statement, and not the inner if statement. Both Python's for and while loops support such an else clause, which is executed only if early exit of the loop has not occurred. Some languages support breaking out of nested loops; in theory circles, these are called multi-level breaks.
The end-loop marker specifies the name of the index variable, which must correspond to the name of the index variable at the start of the for-loop. Some languages (PL/I, Fortran 95, and later) allow a statement label at the start of a for-loop that can be matched by the compiler against the same text on the corresponding end-loop statement.
Because the worst case output size for a range reporting query, measured as a function of the data set size n, can be n itself, much of the research on range reporting data structures has investigated output-sensitive algorithms, where the query time is analyzed in terms of both n and the number of reported points (often denoted k).
The template is used to produce a simple loop of repeated strings. Template parameters [Edit template data] Parameter Description Type Status Number 1 Number of times to repeat Number required String 2 The string to be repeated. Use {{=}} if the string contains an equals sign. String required See also Template:For loop (edit | talk | history | links | watch | logs) Template:Simple recursion ...
However, there are occasions when copy-and-paste programming is considered acceptable or necessary, such as for boilerplate, loop unrolling (when not supported automatically by the compiler), languages with limited metaprogramming facilities, or certain programming idioms, and it is supported by some source code editors in the form of snippets.
A conditional loop has the potential to become an infinite loop when nothing in the loop's body can affect the outcome of the loop's conditional statement. However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language, but many share the same basic ...
