v. t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is ...
Recursion is the process a procedure goes through when one of the steps of the procedure involves invoking the procedure itself. A procedure that goes through recursion is said to be 'recursive'. [ 3 ] To understand recursion, one must recognize the distinction between a procedure and the running of a procedure.
Control flow. v. t. e. In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
For loop. Foreach loop. Infinite loop. Control flow. v. t. e. In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.
Recursion is a technique for representing data whose exact size is unknown to the programmer: the programmer can specify this data with a self-referentialdefinition. There are two types of self-referential definitions: inductive and coinductivedefinitions. Further information: Algebraic data type.
Declarative programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed. Functional and logic programming languages are characterized by a declarative programming style. In logic programming, programs consist of sentences expressed in ...
Don't repeat yourself. " Don't repeat yourself " (DRY) is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place. The DRY principle is stated as "Every piece of ...
e. In programming language theory, lazy evaluation, or call-by-need, [ 1 ] is an evaluation strategy which delays the evaluation of an expression until its value is needed (non-strict evaluation) and which also avoids repeated evaluations (by the use of sharing). [ 2 ][ 3 ] The benefits of lazy evaluation include: The ability to define control ...
