What is an infinite loop? Write the code for an infinite loop. An infinite loop is a sequence of instructions in a computer program which loops endlessly. Example of an infinite loop: Set k = 1 While k < = 5 Display k End While 7. A FOR loop looks like what other loop in a flowchart? A For loop looks like a count-controlled loop. 8. Why is it critical that accumulator variables are properly initialized? An accumulator is used to keep a running total of numbers. In a loop‚ a value is

This is the style used in our textbook Combinatorial Algorithms:

Pseudocode (pronounced SOO-doh-kohd) is a detailed yet readable description of what a computer program or algorithm must do‚ expressed in a formally-styled natural language rather than in a programming language. Pseudocode is sometimes used as a detailed step in the process of developing a program. It allows designers or lead programmers to express the design in great detail and provides programmers a detailed template for the next step of writing code in a specific programming language. Because

PSEUDOCODE STANDARD Example Pseudocode is a kind of structured english for describing algorithms. It allows the designer to focus on the logic of the algorithm without being distracted by details of language syntax. At the same time‚ the pseudocode needs to be complete. It describe the entire logic of the algorithm so that implementation becomes a rote mechanical task of translating line by line into source code. In general the vocabulary used in the pseudocode should be the vocabulary of

Loop Structures (Visual Basic) isual Basic loop structures allow you to run one or more lines of code repetitively. You can repeat the statements in a loop structure until a condition is True‚ until a condition is False‚ a specified number of times‚ or once for each element in a collection. The following illustration shows a loop structure that runs a set of statements until a condition becomes true. Running a set of statements until a condition becomes true Introduction Visual Basic allows

Java For Loops We’ll start with For Loops‚ one of the most common types of loops. The "For" part of "For Loop" seems to have lost its meaning. But you can think of it like this: "Loop FOR a set number of times." The structure of the For Loop is this: for ( start_value; end_value; increment_number ) { //YOUR_CODE_HERE } While Loops Another type of loop you can use in Java is called the while loop. While loops are a lot easier to understand than for loops. Here’s what they look like: while

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:

What is Pseudocode First‚ you need to understand that pseudocode is not a programming language. Pseudocode cannot be compiled nor executed on a computer‚ and there is no real formatting or syntax rules. It is simply one step‚ a very important step‚ in producing the final code. The benefit of pseudocode is that it enables the designer to concentrate on the algorithms without worrying about all the syntactic details of a programming language. In fact‚ you can write pseudocode without even knowing

Count-Controlled Loops and While Loops Count-controlled: control variable (or loop counter) initial value of the control variable increment (or decrement) by which the control variable is modified each iteration through the loop condition that tests for the final value of the control variable A count-controlled repetition will exit after running a certain number of times. The count is kept in a variable called an index or counter. When the index reaches a certain value (the loop bound) the loop will
