The Cambridge Grammar of the English Language does not classify echo questions as a distinct clause type. Rather, it treats them as having the same syntactic form as the stimuli they echo. [1] For example, an echo of an imperative clause is also an imperative clause, as in: A: Bring me the axe. B: Bring you the what?
The Portuguese language is the only major Romance language to use echo answers often, even though it has words for "yes" and "no" proper (sim and não respectively) as well. Portuguese will most commonly answer a polar question in the affirmative by repeating the main verb. For example, one would answer the question, "Tens fome?" ("Are you hungry?"
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
echo began within Multics.After it was programmed in C by Doug McIlroy as a "finger exercise" and proved to be useful, it became part of Version 2 Unix. echo -n in Version 7 replaced prompt, (which behaved like echo but without terminating its output with a line delimiter).
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
Support for code comments is defined by each programming language. The features differ by language, but there are several common attributes that apply throughout. Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span ...

A unit test is code that is written to execute a specific function in the code to be tested and usually targets a small unit of code, such a single method or class. Using a combination of assert statements and other test statements, programmers can create suites of test cases in order to tell if a method or function is being executed properly. [5]
