A do while loop is a control flow statement that executes a block of code and then either repeats or exits depending on a condition. Learn the syntax, examples and comparison with other loop constructs in various programming languages.
A for loop is a computer programming construct that allows repeated execution of a block of code until a condition is met. Learn how to use for loops in different languages, such as C, Fortran and Python, and how to handle loop variables, counters and break statements.
Control flow is the order in which statements, instructions or function calls of an imperative program are executed or evaluated. Learn about the primitives, categories and proposed control structures of control flow in computer science.
A while loop is a control flow statement that repeats code until a condition is false. Learn how to write a while loop in different programming languages, such as C, Java, Python, and more, with examples and diagrams.
Recursion is a method of solving problems by using functions that call themselves from within their own code. Learn about recursive functions, algorithms, data types, and examples in computer science.
Learn about the method of successive over-relaxation (SOR), a variant of the Gauss–Seidel method for solving linear systems of equations. Find out the formulation, convergence rate, algorithm, example and implementation of SOR.
Loop unrolling is a way to optimize a program's execution speed by reducing or eliminating the instructions that control the loop. Learn the advantages, disadvantages, and examples of loop unrolling in C and MIPS assembly language.
In Python 3.x the range() function [29] returns a generator which computes elements of the list on demand. Elements are only generated when they are needed (e.g., when print(r[3]) is evaluated in the following example), so this is an example of lazy or deferred evaluation: >>>
