"while" is an entry controlled loop statement i.e the condition is evaluated first and if it is true the body of the loop is evaluated.This process is repeated until the test condition is false;then the control is transfered out of the loop.
The general form of while is as following
syntax:
while (<condition>)
{
<statements>;
}
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
If you want to execute a statement which is in while loop at least one time you can use do- while loop. this is why because initially first statements will be executed then condition will be checked. but in case of while first condition will be check then statements will be executed
No, why did you think so?
An iteration is an instance of a structured loop statement (for, while or do-while).
It depends on the programming language, however most high-level languages will provide some variant of the standard 'for' loop in addition to some variant of the 'while' and 'do-while' loop.
The do while loop is also called an exit condition loop in c, c++, and java.
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.
There are no "Rules", you only have to remember the syntax:for (; ; ) it is the same thing as:;while () {;}
while (2*2==4) printf ("Still running\n");
#include<stdio.h>
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.
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.
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.
Both are programming commands. A do/while loop will execute at least once. A while loop may not execute at all.
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
"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.
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.
