In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp. If a function has the return type void, the return statement can be used without a value, in which case the program just breaks out of the current function and ...
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
Microsoft Access is designed to scale to support more data and users by linking to multiple Access databases or using a back-end database like Microsoft SQL Server. With the latter design, the amount of data and users can scale to enterprise-level solutions. Microsoft Access's role in web development prior to version 2010 is limited.
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
The return statement, used to return a value from a function The import and from statements, used to import modules whose functions or variables can be used in the current program The match and case statements, an analog of the switch statement construct, that compares an expression against one or more cases as a control-of-flow measure.
The keyword Sub is used to return no value and Function to return a value. When used in the context of a class, a procedure is a method. [27] Each parameter has a data type that can be specified, but if not, defaults to Object for later versions based on .NET and variant for VB6. [28]
Whether or not Foo.bar(5) invokes a function or simply sets an attribute is hidden from the caller. Likewise whether Foo.bar() simply retrieves the value of the attribute, or invokes a function to compute the value returned, is an implementation detail hidden from the caller. If the language uses the attribute syntax the syntax may look like this.
In computer science, a mutator method is a method used to control changes to a variable. They are also widely known as setter methods. Often a setter is accompanied by a getter, which returns the value of the private member variable.
