Which code is executed when the condition is false?

However, the code inside the curly braces is skipped if the condition evaluates to false, and the code after the if statement is executed….Comparison Operators.

What happens if a while loop is false?

While is a pretest loop With pretest loops such as the while loop, the program may never execute the loop statements. If the initial evaluation of the while statement’s true/false expression is false, the program skips all statements of the loop and continues execution after the while statement.

Which loop executes at least once if the condition is false?

With a do while loop the condition is not evaluated until the end of the loop. Because of that a do while loop will always execute at least once. A for-loop always makes sure the condition is true before running the program.

How many times while loop will execute Though condition is false?

The while() loop repeats as long as the condition is true (non-zero). If the condition is false the body of the loop never executes at all.

Which type of loop is while loop?

In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.

What is a false loop?

A while loop checks the condition (well, the expression) behind the while before each iteration and stops executing the loop body when the condition is False . So while False means that the loop body will never execute.

How the execution of while loop will be terminated?

A while loop can also terminate when a break, goto, or return within the statement body is executed. Use continue to terminate the current iteration without exiting the while loop. continue passes control to the next iteration of the while loop. The termination condition is evaluated at the top of the loop.

What loops will always execute at least once?

In the do-while loop, the body of a loop is always executed at least once. After the body is executed, then it checks the condition. If the condition is true, then it will again execute the body of a loop otherwise control is transferred out of the loop.

Which loop executes at least once irrespective of test condition?

Exit Controlled Loops: In this type of loops the test condition is tested or evaluated at the end of loop body. Therefore, the loop body will execute atleast once, irrespective of whether the test condition is true or false. do – while loop is exit controlled loop.

How many times does the loop gets executed?

The main difference between do while loop and while loop is in do while loop the condition is tested at the end of loop body, i.e do while loop is exit controlled whereas the other two loops are entry controlled loops. Note: In do while loop the loop body will execute at least once irrespective of test condition.

How many times the while loop will get executed?

The while(j <= 255) loop will get executed 255 times.

Why do-while loop is executed when the condition is false?

Because in a do-while loop, First not check the condition. After that check the condition. This is the reason that the do-while loop is the loop that is executed when the condition is false.

What is the difference between while loop and DO WHILE LOOP?

In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then and only then the body of a loop is executed. 2. In a do…while loop, the condition is always executed after the body of a loop. It is also called an exit-controlled loop.

What are the different types of looping statements in C?

Depending upon the position of a control statement in a program, looping statement in C is classified into two types: 1. Entry controlled loop 2. Exit controlled loop In an entry control loop in C, a condition is checked before executing the body of a loop.

What happens to the body of a for loop after evaluation?

In for loop the initialization step is excuted if it is there. It is never excuted again. After this condition expression is evaluated and if it is found true then body of loop is excuted after this control goes to third part i.e. increment or decrement if it is defined.
