Thus, in conditional Statements , a condition is present and based on it's truth value the task is performed or rejected. Whereas in Unconditional statement there is no condition associated, thus the task may get rejected but you won't know the reason because you didn't care at all!

The do while loop checks the condition at the end of the loop. This means that the statements inside the loop body will be executed at least once even if the condition is never true. The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once.

What is one significant difference between a while loop and a do-while loop? -A DO-WHILE loop will always execute the code at least once, even if the conditional statement for the WHILE is never true. A WHILE loop is only executed if the conditional statement is true.

In the case of 'if-else' statement, either the 'if' block or the 'else' block will be executed based on the condition. In the case of the 'switch' statement, one case after another will be executed until the break keyword is not found, or the default statement is executed.

while 1 is the same as while true. It means loop forever. The only way to stop the loop is to use a break statement, which is what you're doing with the.

= is used for assigning values to a variable, == is used for comparing two variables, but it ignores the datatype of variable whereas === is used for comparing two variables, but this operator also checks datatype and compares two values.

Do While Executes When Condition is False. The Do Until loop keeps iterating while the condition is false and until the condition is true. The Do While loop simply executes as long as the condition is true.

A definite loop is a loop in which the number of times it is going to execute is known in advance before entering the loop, while an indefinite loop is executed until some condition is satisfied and the number of times it is going to execute is not known in advance.

Unlike the Boolean logical operators "&" and "|," which always evaluate both the operands, conditional logical operators execute the second operand only if necessary. As a result, conditional logical operators are faster than Boolean logical operators and are often preferred.

Yes, there is a huge difference between while and for. The for statement iterates through a collection or iterable object or generator function. The while statement simply loops until a condition is False. ... This gives us a data structure tailor-made for the for statement.

Here is the syntax for the WHILE loop statement: WHILE condition LOOP statements; END LOOP; The condition in the WHILE is a Boolean expression that evaluates to TRUE , FALSE or NULL . ... PL/SQL evaluates the condition in the WHILE clause before each loop iteration.

if statement checks a condition and executes a set of statements when this condition is true, it does not do anything when the condition is false. if-else statement checks a condition and executes a set of statements when this condition is true, it executes another set of statements when the condition is false.

do { statement(s); } while( condition ); Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop executes once before the condition is tested. If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop executes again.
