How do you write a while loop algorithm?

Writing algorithms using the while-statement

1. Assignment statement: variable = expression ;
2. Conditional statements: if ( condition ) statement if ( condition ) statement1 else statement2.
3. Loop (while) statements: while ( condition ) { statement1 statement2 }

How do you write a loop syntax?

Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end.

Can we use if statement in while loop?

And to answer your questions, yes it’s perfectly valid to nest if statements in a while loop.

What is while statement write its syntax?

You use a while statement to continually execute a block of statements while a condition remains true. The general syntax of the while statement is: while (expression) { statement } First, the while statement evaluates expression, which must return a boolean value.

What is the proper syntax for writing a while loop in Python?

Python while loops (which are often called do while loops in other languages) execute a block of code while a statement evaluates to true. The syntax for a while loop is: while [your condition]. A while loop should eventually evaluate to false otherwise it will not stop.

Can we use while in algorithm?

The while loop is used to repeat a section of code an unknown number of times until a specific condition is met. In this case, we could use a while loop to determine that answer: The “pseudocode” for such an algorithm is: while the number is bigger than one keep dividing it by two.

How DO…WHILE LOOP works?

How do…while loop works? 1 The body of do…while loop is executed at first. 2 Then the test-expression is evaluated. 3 If the test-expression is true, the body of loop is executed. 4 When the test-expression is false, do…while loop terminates. More

What is the difference between while and DO-WHILE loop in C?

The critical difference between the while and do-while loop is that in while loop the while is written at the beginning. In do-while loop, the while condition is written at the end and terminates with a semi-colon (;) The following loop program in C illustrates the working of a do-while loop:

What is the use of do while in Java?

while (true){ // your code goes here }. The Java programming language also provides a do-while statement, which can be expressed as follows: do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top.

How many times does the DO WHILE loop run in C++?

In total, the do…while loop will run for 10 times. Finally, when the value of i is 11, the test-expression evaluates to false and hence terminates the loop. If the test expression in the while and do…while loop never evaluates to false, the body of loop will run forever.
