Explain Difference Between Do-while and While Loop With Example

While loop is entry controlled loop whereas do while is exit controlled loop. The do-while loop is a post-test loop.

Difference Between While And Do While Explained With Examples

The main feature of the while loop isits an entry controlled loop.

. At least 1 iteration is possible. 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.

While i 10. The while and do-while loop are almost similar in C. 5 rows Here the main difference between a while loop and do while loop is that while loop check.

No iteration is possible without satisfying loop-entry condition. Benefit of the WHILE loop is when you are unsure how many iterations are required. 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.

PrintfSum of 1 to 10 is da. In do-while loop the loop body will execute at least once irrespective of test condition. Here is a list of the differences present between while and do-while loop in C C.

Although Do While loop and While loop in Java looks similar they differ in the order of execution. Condition is checked later. The condition is executed at least once even if the condition computes to false during the first iteration.

While the loop is an entry control loop because firstly the condition is checked then the. The do-while loop is very similar to that of the while loop. The while loop is a pre-test loop but do-while is a post-test loop.

Since condition is checked first statements may or may not get executed. 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. A loop that executes the loop body first and then checks for a condition is known as an exit controlled 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. 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. What is a do-while loop.

Except for the fact that while tests the condition first and then executes whereas do-while loop first executes then tests the condition. It is also known as an exit-controlled loop. 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.

Body of loop Following is the flowchart of while loop. Solution for Explain the difference between while loop and do while loop with an example for each one. How to use do while loop in Scala var numberOfDonutsBaked 0 do numberOfDonutsBaked 1 printlnsNumber of donuts baked.

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. So the While loop executes the code block only if the condition is True. Do a a i.

Checks boundary condition even before 1st iteration. The do-while loop executes the body and then evaluates number 10 until number 10 is false. For example this prints nothing.

Two most important loops are while loop and do-while loop. While loop and do-while. The while loop first evaluates number 10 and then executes the body until number 10 is false.

Since the do-while loop checks the condition only after it. Difference between while-loop and do-while-loop. Since condition is checked later the body statements will execute at least once.

Int i 11. Difference Between while and do-while loop in C C Java. The controlling condition is present at the end of the loop.

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. 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. On the other hand a loop that checks for condition first and run the loop body can be categorized as entry.

Thus it is an example of a type of Exit Control Loop. In Java While the condition is tested at the beginning of the loop and if the condition is True then only statements in that loop will be executed. Example while condition statements.

But the only difference is that this loop checks for the conditions available after we check a statement. Block of code inside the while statement may or may not be executed depending on the condition. It is known as entry controlled 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. The main difference between a do-while loop and while loop is in the do-while loop the condition is tested at the end of the loop body ie do-while loop is exit controlled whereas the other two loops are entry controlled loops. The main feature of the do while loops is it is an exit controlled loop.

Checks boundary condition after 1st loop iteration. Difference between While and Do While in Java. For example Do-While loop.

It saves writing code several times for same task.
