Logical Operators and While Loops: Transcript

CS303E Elements of Computers and Programming Quote of the Day Optimism is an occupational hazard of programming testing is the treatment K Beck Logical Operators What are they Operators that act on . Chapter. 4. Repeated Tasks are for Computers. Think back to any very difficult quantitative problem that you had to solve in some science class. How long did it take?. How many times did you solve it?. Another Type of Indefinite Loop. The . do/while. loop. do/while. loop. : . Performs its test at the . end. of each repetition.. Guarantees that the loop's . {}. body will run at least once.. do {. AGEC 641 Lab, Fall 2011. Mario Andres Fernandez. Based on material written by . McCarl. and . Elbakidze. ; Improved upon by many previous lab instructors.. Special thanks to . Yuquan. “Wolfgang” Zhang. By Ms. Bellacera. While Loop Form. w. hile (condition). {. statement;. statement;. }. //executes an //. unknown. //number of times. i. nt z=0;. w. hile (z<10). {. z=z+1;. }. c. out<<“z is “<<z<<endl;. Iteration. We’ve seen many places where repetition is necessary in a problem.. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. Jumps . Logical Operators. The different logical operators found in Java. Rational Operators. The different . rational . operators found in Java. . Jumps . A jump is also known as a branch . A jump is when you program skips certain steps to move on to another block of code . CS . 106. While loop syntax. Q: The syntax for a while statement is:. while _______________ :. _____________ . . A: while <boolean expression>:. <body>. or, . condition.

If you read the instructions on most shampoo bottles, “Lather, rinse, repeat” is what they say. . This has a problem that it will never stop!. How would you fix it?. One if statement inside another one. An if statement inside a loop. A loop inside an if statement. Control structures can be nested inside each other to any degree you need . Nested loops. The general principle of nesting loops is that the inner loop must completely finish its execution before the next iteration of the outer loop starts. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. There are situations where loops are needed but there is no way to determine ahead of time how many times they will run, this is an . Why use loops in C language?. The looping simplifies the complex problems into the easy ones. It enables us to alter the flow of the program so that instead of writing the same code again and again, we can repeat the same code for a finite number of times. For example, if we need to print the first 10 natural numbers then, instead of using the .
