Example explained. Line 1: #include is a header file library that lets us work with input and output objects, such as cout (used in line 5). Header files add functionality to C programs. Line 2: using namespace std means that we can use names for objects and variables from the standard library. While Statement (C); 2 minutes to read +2; In this article. Executes statement repeatedly until expression evaluates to zero. Syntax while ( expression ) statement Remarks. The test of expression takes place before each execution of the loop; therefore, a while loop executes zero or more times.expression must be of an integral type, a pointer type, or a class type with an. Mar 19, 2019 do-while - Sama seperti perulangan while, dalam perancangan perulangan do-while ini kita harus memahami alur logika program yang dibuat. Banyaknya perulangan di tentukan pada saat program mencapai kondisi FALSE. Kesalahan dalam alur logika akan membuat C. Access denied while executing c source file. Ask Question Asked 1 year, 4 months ago. I am unable to execute my program which i have written on DEV-CPP IDE.

- Here, key point of the while loop is that the loop might not ever run. When the condition is tested and the result is false, the loop body will be skipped and the first statement after the while loop will be executed.
- This is a piece of code that repeats while a certain condition is true. In this tutorial, we will be learning how to use the two most basic kinds of loops - the while loop and the for loop. The while loop is the simplest of loops in C and pretty much does exactly what we defined in the basic introductory paragraph.

Unlike for and while loops, which test the loop condition at the top of the loop, the do..while loop checks its condition at the bottom of the loop.
A do..while loop is similar to a while loop, except that a do..while loop is guaranteed to execute at least one time.
Syntax
The syntax of a do..while loop in C++ is −
Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop execute once before the condition is tested.
If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop execute again. This process repeats until the given condition becomes false.

In the previous tutorial we learned while loop in C. A do while loop is similar to while loop with one exception that it executes the statements inside the body of do-while before checking the condition. On the other hand in the while loop, first the condition is checked and then the statements in while loop are executed. So you can say that if a condition is false at the first place then the do while would run once, however the while loop would not run at all.

Explanation: As I mentioned in the beginning of this guide that do-while runs at least once even if the condition is false because the condition is evaluated, after the execution of the body of loop.
