A Loop executes the sequence of statements many times until the stated condition becomes false.
In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once, and then either repeatedly executes the block, or stops executing it, depending on a given boolean condition at the end of the block. The do while construct consists of a process symbol and a condition. First, the code within the block is executed, and then the condition is evaluated. If the condition is true the code within the block is executed again. This repeats until the condition becomes false.
Do while loop
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. Note that it is possible, and in some cases desirable, for the condition to always evaluate to true, creating an infinite loop. When such a loop is created intentionally, there is usually another control structure such as a break statement that controls termination of the loop. For example:.

Documentation Help Center. An expression is true when its result is nonempty and contains only nonzero elements logical or real numeric. Otherwise, the expression is false. Use a while loop to calculate factorial Count the number of lines of code in the file magic. Skip blank lines and comments using a continue statement. Sum a sequence of random numbers until the next random number is greater than an upper limit.
These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop. On the other hand, the do-while loop verifies the condition after the execution of the statements inside the loop. Furthermore, the while loop is known as the entry-controlled loop. Conversely, the do while loop is called the exit controlled loop.
What is the difference between while and do-while loops in C?
In this tutorial you will learn how to repeat a series of actions using loops in PHP. Loops are used to execute the same block of code again and again, as long as a certain condition is met. The basic idea behind a loop is to automate the repetitive tasks within a program to save the time and effort.
How to begin Get the book. Practice problems Quizzes. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming -- many programs or websites that produce extremely complex output such as a message board are really only executing a single task many times.
