Do While Loop Glossary Entry Embedded Systems The loop body is always executed at least once (contrast to while loops) the condition to reenter the loop is evaluated after – if met, the loop body is repeated, otherwise the loop exits. A do…while loop in c is similar to the while loop except that the condition is always executed after the body of a loop. it is also called an exit controlled loop.
Do While Loop Pdf Software Development Control Flow In this article we will see the repetitive statements to create loops to create programs in c language for embedded systems. The do while loop statement executes the nested statement repeatedly as long as the condition evaluates to the boolean value true. unlike the while statement, the condition is evaluated at end of every iteration, resulting in the nested statement being executed at least once. This document explains the usage of the three main loop structures in c: do while, while, and for. these loops are essential in microcontroller programming to execute repetitive tasks. A do while loop is preferred when it is essential that the loop body executes at least once, regardless of the condition. this is particularly useful in scenarios where user input is required, ensuring that the prompt is displayed before any condition checks.

In ‘c’ there are 3 types of loop statements. do…while loop. here while, for, and do all these are reserved keywords of ‘c’ standard. while loop means, repeat execution of code inside the loop body until expression evaluates to false (0). it only has one part: the condition. Use for loop when the number of iterations is known beforehand, i.e. the number of times the loop body is needed to be executed is known. use while loops where the exact number of iterations is not known, but the loop termination condition is known. The expression “while (1)” is commonly used in the field of embedded systems. it represents an infinite loop, where the code inside the loop will be executed repeatedly as long as the condition “1” remains true. Due to this property, the do while loop is also called exit controlled or post tested loop. when the test condition is evaluated as true, the program control goes to the start of the loop and the body is executed once more.
