What is while loop explain with example?
What is while loop explain with example?
A “While” Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10”.
What are examples of do while loop programs?
Program to print table for the given number using do while loop
- #include
- int main(){
- int i=1,number=0;
- printf(“Enter a number: “);
- scanf(“%d”,&number);
- do{
- printf(“%d \n”,(number*i));
- i++;
Is there do while loop in JavaScript?
while Loops. A JavaScript do… while loop executes a statement once and then it checks if a condition is true. If the condition is true, the loop will be executed again.
Do while loops explained?
The do while loop checks the condition at the end of the loop. This means that the statements inside the loop body will be executed at least once even if the condition is never true. The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once.
What is the difference between while loop and do while loop explain with example?
do-while loop: do while loop is similar to while loop with the only difference that it checks for the condition after executing the statements, and therefore is an example of Exit Control Loop.
What is while and do while loop?
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.
What is a Do While loop example in real life?
Do-while loops are sometimes useful if you want the code to output some sort of menu to a screen so that the menu is guaranteed to show once. Example: int data; do { cout << “Enter 0 to quit: “; cin >> data; cout << endl << endl; } while (data != 0);
Do While loop in Java example with output?
DoWhileExample.java
- public class DoWhileExample {
- public static void main(String[] args) {
- int i=1;
- do{
- System.out.println(i);
- i++;
- }while(i<=10);
- }
How does a while loop start *?
First, outside of the loop, the count variable is set to 1. Second, before the first iteration begins, the while statement checks if count is less than 10 and execute the statements inside the loop body.
Do While and while Difference example?
Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop….Comparison Chart.
| Basis for comparison | while | do-while |
|---|---|---|
| General Form | while ( condition) { statements; //body of loop } | do{ . statements; // body of loop. . } while( Condition ); |
Which is better do while or while?
Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true is any nonzero value. The loop iterates while the condition is true….Output.
| While Loop | Do-While Loop |
|---|---|
| while(condition){ //statement } | do{ //statement }while(condition); |
Do While VS while example?
Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true is any nonzero value. The loop iterates while the condition is true….Output.
| While Loop | Do-While Loop |
|---|---|
| The while loop may run zero or more times | Do-While may run more than one times but at least once. |
What is an example of while loop?
A while loop is a control flow structure which repeatedly executes a block of code indefinite no. of times until the given condition becomes false. For example, say, you want to count the occurrence of odd numbers in a range. Some technical references call it a pre-test loop as it checks the condition before every iteration.
What is while loop in Java?
while loop: A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition.
Do WHILE loop in Java?
Java while and do…while Loop Java while loop. Java while loop is used to run a specific code until a certain condition is met. Flowchart of while loop. Here is how this program works. Java do…while loop. The do…while loop is similar to while loop. for and while loops. The for loop is used when the number of iterations is known.
What is loop in JavaScript?
Loops in JavaScript. Looping in programming languages is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to true.
