In many computer programming languages, a do while loop is a control flow statement that executes a block of code and then either repeats the block or exits the loop depending on a given boolean condition. The do while construct consists of a process symbol and a condition. First the code within the block is executed.
The while loop in the code above reads characters by calling GetChar (), skipping the statements in the body of the loop if the characters are spaces. Exception handling [ edit ]
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...

However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language, but many share the same basic structure and/or concept. The While loop and the For loop are the two most common types of conditional loops in most programming languages.
Fortran's equivalent of the for loop is the DO loop, using the keyword do instead of for, The syntax of Fortran's DO loop is: DO label counter = first , last , step statements label statement The following two examples behave equivalently to the three argument for-loop in other languages, initializing the counter variable to 1, incrementing by ...
Loops using while, repeat until or do, and for statements; switch a.k.a. case statements, a form of multiway branching; These new language mechanisms replaced equivalent flows which previously would have been written using gotos and ifs. Multi-way branching replaces the "computed goto" in which the instruction to jump to is determined ...
