Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...
MPW provided a command line environment and tools, including 68k and PowerPC assemblers as well as Pascal, C and C++ compilers. The shell environment is somewhat similar to Unix shells in design, but is designed around the Macintosh's character set and GUI, replacing the usual terminal environment with a "worksheet" interface, allowing the user ...
a b c Deep breaks may be accomplished in APL, C, C++ and C# through the use of labels and gotos. a Iteration over objects was added in PHP 5. a b c A counting loop can be simulated by iterating over an incrementing list or generator, for instance, Python's range() .
Until COBOL 2002, if a D or d was in column 7, it would define a "debugging line" which would be ignored unless the compiler was instructed to compile it. Cobra. Cobra supports block comments with "/#... #/" which is like the "/*... */" often found in C-based languages, but with two differences
Most simple words execute the same code whether they are typed on a command line, or embedded in code. When compiling these, the compiler simply places code or a threaded pointer to the word. [28] The classic examples of compile-time words are the control structures such as IF and WHILE. Almost all of Forth's control structures and almost all ...
The core syntax of the C# language is similar to that of other C-style languages such as C, C++ and Java, particularly: Semicolons are used to denote the end of a statement. Curly brackets are used to group statements. Statements are commonly grouped into methods (functions), methods into classes, and classes into namespaces.
CH can interact with existing C/C++ libraries and call C/C++ functions from CH script. [16] As a C/C++ interpreter, CH can be used as a scripting engine and extension language for applications. Pointers to arrays or variables can be passed and shared in both C-compiled and CH scripting contexts. One example of an embedded CH scripting ...
the invocation of a compiler together with source to compile and instructions for executing the compiled program. Certain dynamic languages for scripting, such as AWK, sed, and Perl, have traditionally been adept at expressing one-liners. Shell interpreters such as Unix shells or Windows PowerShell allow for the construction of powerful one-liners.
