Do loops do while statements?
A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given boolean condition at the end of the block. Some languages may use a different naming convention for this type of loop.
What should be included in a while loop?
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”.
Can we use do without while?
Avoiding the do/while loop is a recommendation included in the C++ Core Guidelines as ES. 75, avoid do-statements.
Which statement is required from loop?
Explanation: If there is no BREAK statement, while loop runs continuously util the computer hangs. BREAK causes the loop to break once and the statement below the while if any will be executed.
Do while loop is useful when we want that statement within the loop must be executed?
Explanation: in case the condition is true,the control goes back to beginning of loop.. this means that the statements inside the loop are executed before the condition is tested.so do while loop should be used in all scenarios where the loop body needs to be executed at least once.
What does the while statement do?
while statement creates a loop that executes a specified statement until the test condition evaluates to false. The condition is evaluated after executing the statement, resulting in the specified statement executing at least once.
Do while loop do not execute the statement while condition is false True or false?
If the condition is true the code within the block is executed again. This repeats until the condition becomes false. If the expression is false, the loop terminates and control transfers to the statement following the do-while loop.
Can we use continue statement without using loop?
The continue statement can be used with any other loop also like while or do while in a similar way as it is used with for loop above. Exercise Problem: Given a number n, print triangular pattern. We are allowed to use only one loop.
Which statements is used to skip statements in a loop?
The break and continue statements are the jump statements that are used to skip some statements inside the loop or terminate the loop immediately without checking the test expression.
What is the Continue statement used for?
A continue statement ends the current iteration of a loop. Program control is passed from the continue statement to the end of the loop body. A continue statement can only appear within the body of an iterative statement, such as do , for , or while .
