Lecture 4 Looping Statements Pdf Control Flow Software Engineering The document is a lecture on repetition and loop statements in computer programming, specifically focusing on different types of loops such as count controlled and event controlled loops. Statements should take place. there are number of situations, where it is necessary to change the order of execution of statements based on certain conditions (decision making) or repeat a group of statements (forming loops) until certain specified conditions are met.
Lect 4 Looping Statements Download Free Pdf Control Flow Computing Early languages relied heavily on unstructured flow, especially goto’s. common uses of goto have been captured by structured control statements. with this, we can implement loops, if statements, and case statements. in fact, we only need. to build a universal machine (one that is turing complete). Loop instructions can be nested –with the following observations: the inner loop must be included inside the outer loop for each value of the counter of the outer instruction, the counter of the inner instruction takes all its values. Control flow refers to the order in which statements within a program execute. while programs typically follow a sequential flow from top to bottom, there are scenarios where we need more flexibility. A portion of a program that repeats a statement or a group of statements is called a loop. the statement or group of statements to be repeated is called the body of the loop. a loop could be used to compute grades for each student in a class. there must be a means of exiting the loop.

Working: step1: the loop variable is initialized with some value and then it has been tested for the condition. step2: if the condition returns true then the statements inside the body of while loop are executed else control comes out of the loop. In high level programming languages, this is accomplished with control flow statements that allow you to alter the sequential flow. control flow statements fall into two general categories: conditional branching and looping. All the 3 control structures and its flow of execution is represented in the flow charts given below. Statement • the “while” statement is used to carry out looping operations, in which a group of statements is executed repeatedly, as long as some condition remains satisfied.
