In most computer programming languages, a do while loop, sometimes just called a do loop, is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. Note though that unlike most languages, Fortran's do loop is actually analogous to the for loop.
The do while construct consists of a block of code 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. Because do while loops check the condition after the block is executed, the control structure is often also known as a post-test loop. Contrast with the while loop, which tests the condition before the code within the block is executed.
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 allows termination of the loop.
Some languages may use a different naming convention for this type of loop. For example, the Pascal language has a "repeat until" loop, which continues to run until the control expression is true (and then terminates) - whereas a "do-while" loop runs while the control expression is true (and terminates once the expression becomes false).

Which loop is also called an exit-condition loop in C programming?
The do while loop is also called an exit condition loop in c, c++, and java.
What is the definition of 'nested' in C programming?
In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.
What are the Rules associated with for loop in C programming?
There are no "Rules", you only have to remember the syntax:for (; ; ) it is the same thing as:;while () {;}
How infinite loop is created using while in C programming?
while (2*2==4) printf ("Still running\n");
How do you use loop in C programming?
#include<stdio.h>
How can you define null statement in loop in C programming?
If you are using for loop for(;;); or you can also define condition and iterations but the loop has to close there itself without any statement inside it. In the similar way you can define while and do while loop without any statement.
How many rows do the update queries fetch inside a while loop?
Is your question about C programming or Oracle Database. From the stand point of C programming your question does not make sense. Perhaps you need to rephrase the question.
What is difference between select Case statement and nested loop in c programming in UNIX?
UNIX has no bearing on the C language; it is cross-platform. There is no select/case in C, you probably meant switch/case. However, a switch/case is a conditional jump while a nested loop is a loop within a loop. Besides the C language they have nothing in common with each other.
What is the Difference between while and do while?
Both are programming commands. A do/while loop will execute at least once. A while loop may not execute at all.
What is a loop type?
A Loop is a programming language construct that instructs the processor to repeat a sequence of operations a number of times until a specific condition is reached. There are different types of loops. They are: * for loop * while loop * do while loop
What is a dowhile statement in C programming?
"do statement while (...);" is a loop which does at least one iteration even if the condition after while is false. When, for instance, "while(...) statement" does not iterate at all if the condition after while is false.
How can I create a knot for loop in my programming code?
To create a knot for loop in programming code, you can use a loop structure that repeats a block of code a specific number of times or until a certain condition is met. This loop allows you to iterate through a sequence of instructions multiple times. You can use keywords like "for" or "while" in languages like Python, Java, or C to implement a knot for loop.
