for (initialization; condition; final_expression) { } for (key in object) { } for (variable of iterable) { } while (condition) { } do { } while (condition) for each (variable in object) { } // ECMAScript for XML Loops in JavaScript typically help solve problems which involve repeating ...

As one of the most basic functions in programming, loops are an important piece to nearly every programming language. Loops enable developers to set certain portions of their code to repeat through a number of loops which are referred to as iterations. This topic covers using multiple types of loops...

A loop statement executes a group of statements repeatedly until a condition is met. There are 3 types of primitive loops in C++: for, while, and do...while. while (condition) statement ; do statement while (expression) ; for (for-init-statement ; condition ; expression) statement ; for (f...

What is Apache Hadoop? The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computa...

SQOOP Server configuration files are stored in server/config directory of distributed artifact along side with other configuration files of Tomcat (to host SQOOP server). File sqoop_bootstrap.properties specifies which configuration provider should be used for loading configuration for rest of Sq...

A loop is a sequence of instruction(s) that is continually repeated until a certain condition is reached. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming. A loop lets you write a very simple statement to produce a significan...

Iterate over column vector A common source of bugs is trying to loop over the elements of a column vector. A column vector is treated like a matrix with one column. (There is actually no distinction in Matlab.) The for loop runs once with the loop variable set to the column. % Prints once: [3,...

Loops are a fundamental aspect of programming. They allow programmers to create code that repeats for some given number of repetitions, or iterations. The number of iterations can be explicit (6 iterations, for example), or continue until some condition is met ('until Hell freezes over'). This topi...

When looping over internal tables, it is generally preferable to ASSIGN to a field symbol rather than loop INTO a work area. Assigning field symbols simply updates their reference to point to the next line of the internal table during each iteration, whereas using INTO results in the line of the t...
