Types of loops * while * Counter-controlled * Sentinel-controlled * State-controlled * for * foreach * do…while 1. WHILE STATEMENT * Simplest and most frequently used loop * Syntax : while (conditional expression) statement(s); * Expression – sometimes called loop condition * Returns a Boolean result of true or false * No semicolon after the conditional expression * Null body→ empty bodied loop→ infinite loop

Do-While‚ and Do-Until conditional loops. Describe the implications of an infinite loop. Assignment Requirements Answer: I. Short Answer Review Questions 1-5‚ starting on page 213 1. You visually set them apart from surrounding code. 2. A pretest loop is a loop tests the conditions before performing the iteration. A posttest loop performs the iteration then test the condition. 3. A condition controlled loop repeats a specific number of times. 4. A count-controlled loop repeats a specific number of times

Infinite Surds Around 800 b.c.e‚ a young Indian scholar by the name of Baudhayana sat in his household studying manuscripts of previous mathematicians. He soon began his own research in mathematics and stumbled across a concept used in common mathematics today. This concept was added to a series of texts known as the Shulba Sastras. Today‚ the concept added to these books is known as square roots. Much like subtracting a number is the opposite of adding a number‚ the square root of a number is

Ch 5) 1.) Describe the difference between pretest loops and posttest loops. 2.) What is a conditioned-controlled loop. 3.) What is a count-controlled loop. 4.) What is an infinite loop. Write the code for an infinite loop. 5.) Design a While loop that lets the user enter a number. The number should be multiplied by 10‚ and the result stored in a variable named product. The loop should stop once product contains a value > 100. 6.) Design a For loop that displays the following set of numbers:

Hyper loop The hyper loop consists of a pair of steel tubes‚ normally elevated‚ which are evacuated to 0.015 psi. This not quite a hard vacuum but "soft" enough that relatively ordinary equipment can be used to maintain it‚ and some tiny leaks can be tolerated. This is about the same pressure as a spacecraft flying at about 30 miles would feel. Pretty low drag‚ but far from zero‚ especially at the proposed 760mph‚ approximately 1/1000th of sea-level drag. The vehicle is substantially smaller

POSITION PAPER ON THE OODA LOOP 1. The OODA loop is a critical thinking and decision making tool used by the military‚ businesses and regular people because it is one of the best. While many processes require step by step obedience‚ any of the steps in the OODA loop can be put into the “wrong” order to fit the needs of the situation. OODA stands for observe‚ orient‚ decide‚ act. 2. Observation is where an individual soaks up raw data and sorts it into relevant and non-relevant. Without the

used to represent Java’s equal to operator. 6. Java’s for loop is an example of a(n) counter-controlled loop. 7. When a while loop or a for loop is coded inside another while loop or for loop‚ the inner loop is called a(n) nested loop.. 8. A(n) sentinel is a special value that denotes the end of a list and is used to terminate loop processing when reading input values from a user‚ or a data file. 9. A(n) off-by-one error occurs when a loop is executed one too many‚ or one too few times due to an
