MATLAB; Pascal although Object Pascal / Delphi do have a function IfThen to do the same (with caveats) Rust The if..else construct is an expression and can be used to get the same functionality. [27] Scala; XProfan PowerShell (in old versions) an elegant workaround is to use (<value for true>,<value for false>)[!(<condition>)] [28]
Some compiled languages such as Ada and Fortran, and some scripting languages such as IDL, MATLAB, and S-Lang, have native support for vectorized operations on arrays. For example, to perform an element by element sum of two arrays, a and b to produce a third c , it is only necessary to write
Supports testing of MPI and OpenMP based procedures. A fully object-oriented implementation using Fortran 2003 is now available. In use with a range of legacy and new Fortran code. ObjexxFTK:UnitTest [266] User writes Fortran tests: Python script automatically finds all tests and generates the Fortran test driver. Supports F77-F2003.
In Object Pascal, D, Java, C#, and Python a finally clause can be added to the try construct. No matter how control leaves the try the code inside the finally clause is guaranteed to execute. This is useful when writing code that must relinquish an expensive resource (such as an opened file or a database connection) when finished processing:
In programming languages with a built-in Boolean data type, such as Pascal, C, Python or Java, the comparison operators such as > and ≠ are usually defined to return a Boolean value. Conditional and iterative commands may be defined to test Boolean-valued expressions.
Stack Overflow is written in C# using the ASP.NET MVC (Model–View–Controller) framework, and Microsoft SQL Server for the database [38] and the Dapper object-relational mapper used for data access. [39]
find the value (if any) that is bound to a given key. The argument to this operation is the key, and the value is returned from the operation. If no value is found, some lookup functions raise an exception, while others return a default value (such as zero, null, or a specific value passed to the constructor).
Other people's benchmark data may have some value to others, but proper interpretation brings many challenges. The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and ...
