Explain Difference Between Do-while and While Loop With Example

Benefit of the WHILE loop is when you are unsure how many iterations are required. Difference between While and Do While in Java Although Do While loop and While loop in Java looks similar they differ in the order of execution.

Difference Between While Loop And Do While Loop While Loop Vs Do While Loop Youtube

While loop is entry controlled loop whereas do while is exit controlled loop.

. It saves writing code several times for same task. Here is a list of the differences present between while and do-while loop in C C. Do- while loop.

The while loop is pre-test loop where firstly the condition is checked and if the condition is true then only the statements of the while loop execute. For example this prints nothing. PrintfSum of 1 to 10 is da.

While loops checks the condition frist then and executes the statement whereas do while loop will execute the statement at least once thence the conditions is checked. While loop and do-while. Two most important loops are while loop and do-while loop.

On the other hand the do-while loop verifies the condition after the execution of the statements inside the loop. Since condition is checked later the body statements will execute at least once. In the do-while statement first the instructions in the do block are executed and then the condition in the while block is tested.

The do-while loop is very similar to that of the while loop. In a nutshell the structure of a while loop is very similar to that of a do-while loop but the main difference lies in the fact that the while loop evaluates the condition first before executing the statements whereas the do-while loop executes the statements first before evaluating the condition of the loop. Difference Between while and do-while loop in C C Java.

How to use do while loop in Scala var numberOfDonutsBaked 0 do numberOfDonutsBaked 1 printlnsNumber of donuts baked. The main feature of the while loop isits an entry controlled loop. C Loops Explained with Examples For Loop Do While and While Loops are very basic and very useful programming facility that facilitates programmer to execute any block of code lines repeatedly and can be controlled as per conditions added by programmer.

Whilei. A loop that executes the loop body first and then checks for a condition is known as an exit controlled loop. At least 1 iteration is possible.

This means the statements in the do while loop are executed at least once. In Java While the condition is tested at the beginning of the loop and if the condition is True then only statements in. The only difference is unlike while loop in do-while loop condition is checked after the loop statements are executed.

So the do while statement will at least execute the code once even if the condition is false at the very first time. While loop checks the condition first and then executes the statements whereas do while loop will execute the statements at least once then the condition is checked. Even if the condition fails for the first time itself.

The main feature of the do while loops is it is an exit controlled loop. The do-while loop is a post-test loop. While i 10.

While the loop is an entry control loop because firstly the condition is checked then the. What is a do-while loop. Difference between while-loop and do-while-loop.

10 rows Condition is checked later. Do-while loop in C. The do-while loop executes the body and then evaluates number 10 until number 10 is false.

C Do-While Loop Example Here is a simple example to find the sum of 1 to 10 using the do-while loop include include void main int i 1a 0. For example Do-While loop. Do a a i.

The while loop first evaluates number 10 and then executes the body until number 10 is false. The difference between a while constructs from Step 1 versus a do while is that any expressions within the do will be running at least once regardless of the condition within the while clause. Since condition is checked first statements may or may not get executed.

It is known as entry controlled loop. Both are the difference from each other if we talk about the main difference then the main difference between while loop and do-while loop is that while loop is a condition that appears at the start of the loop whereas Do-while is a condition that appears at the end of the loop. Since the do-while loop checks the condition only after it.

On the other hand a loop that checks for condition first and run the loop body can be categorized as entry. Here the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop. Int i 11.

But the only difference is that this loop checks for the conditions available after we check a statement. Checks boundary condition after 1st loop iteration. The FOR loop is often used when you usually know how many times you would like the program which means it will run that program until the number of times is complete before it terminates itselfThe WHILE loop works in a similar manner but requires a conditional statement.

The while loop is a pre-test loop but do-while is a post-test loop. Furthermore the while loop is known as the entry-controlled loop. Checks boundary condition even before 1st iteration.

Its syntax is-do body of the loop while test condition. 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. No iteration is possible without satisfying loop-entry condition.

- This is similar to while loop. Unlike the while loop which tests the condition before the code within the block is executed the do-while loop is an exit-condition loop in the sense that the code must always be executed first and then the expression or test condition examined. Thus it is an example of a type of Exit Control Loop.
