How does a while loop work in C?
A while loop in C programming repeatedly executes a target statement as long as a given condition is true.
What is the general form of do while statement explain with example?
The general syntax of the do – while is: do { statement(s) } while (expression); Instead of evaluating the expression at the top of the loop, do – while evaluates the expression at the bottom. Thus, the statements within the block associated with a do – while are executed at least once.
Do-while statements in C language?
The expression in a do-while statement is evaluated after the body of the loop is executed. Therefore, the body of the loop is always executed at least once. The expression must have arithmetic or pointer type.
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 a Do While loop example in real life?
Real World Example, Go to the bath room: DO { Check_Door_Lock(); } WHILE (WAIT_WHILE_DOOR_IS_LOCKED()); after the loop is done then the WAIT_WHILE_DOOR_IS_LOCKED() has returned a false value, so it isn’t locked anymore, thus, the whole loop ends.
What is do-while and 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.
Do WHILE loop in C with example?
There is given the simple program of c language do while loop where we are printing the table of 1. The do-while loop will run infinite times if we pass any non-zero value as the conditional expression.
How to create endless loops in C programming?
– int i = 1: initializes the i variable – i <= num: runs the loop as long as i is less than or equal to num – ++i: increases the i variable by 1 in each iteration
Do while vs while loop?
While loop is entry controlled loop whereas do while is exit controlled loop. In the while loop, we do not need to add a semicolon at the end of a while condition but we need to add a semicolon at the end of the while condition in the do while loop.
Do WHILE loop in C language?
In the C programming language, the do-while loop statement is also similar to a while loop in the C programming language. In this, first of all, the loop’s body is executed then the condition is checked. In the do-while loop, we have to perform three steps: Initialization Test Condition Increment and decrement
