Engineering Innovation: Electronics Lab/MakerSpace
Published in M. Ann Garrison Darrin, Jerry A. Krill, Infusing Innovation into Organizations, 2016
Here, we are creating a code block that will be run repeatedly, commonly referred to as a loop. This is a special loop that you need to be careful with as there is no initial stopping point. A while loop will run while its condition is evaluated to true. The condition in this case is True, which always evaluates to true; therefore, this loop will not stop unless either a line inside the loop breaks it, or the user kills the process. In our code, there is no line to break it out of the loop, so the program will need to be killed to stop it. if GPIO.input(buttonPin) == 1:
Semantics of concurrent protocols
Published in Uri Abraham, Models for Concurrency, 2020
The structure of the procedures follows the definition given in subsection 1.1. Pitcher for example is a while instruction. The condition of this while loop is the sentence true which is always evaluated to true, of course, and hence the loop is executed forever. The body of this loop is itself a concatenated instruction obtained by concatenating two external instructions, obtain(a) and throw(a).
C Programming

One of the important properties of structured control constructs is that they maintain their structure property when nested. For example, a while loop can be nested inside an if-then-else as illustrated in Figure 13.4. Or an if statement, function calls, and a while loop can be nested inside a separate while loop.

Going into more detail about the algorithm, we describe about the terminate condition of the two while loops in the algorithm. The first while loop is for try actions. In every try action, the algorithm attaches string whose length is at least one no matter what applicable rules remain so that the length of the path reaches m eventually. This causes no problem because all we want to do is to count the number of try actions. The algorithm can compensate time to try actions afterward by adjusting parameter . On the other hand, the second while loop is for recall actions. In case of recall action, the algorithm checks whether or not becomes the empty set. If becomes the empty set, the algorithm sets to . Actually, the algorithm can substitute any large value to as long as will never be chosen in the min operation for . After the substitution, ‘break statement’ is executed so as to exit the while loop.
Elementary operations: a novel concept for source-level timing estimation

The output of the entire process is application profile as an abstract model written in an XML structure. In it, the original application source code is transformed into a multi-level structure of elementary operations organized in loops, branches and sequences. Each application is composed of one or more procedures which directly correspond to procedures (functions) in original C source code. Procedures can contain any number of loops, branches or operations. Loop represents a for or a while loop, and branch represents an if-else or switch-case conditional constructs. Loops and branches can have any number of loops, branches and operations as sub-elements. Operation represents a single statement or a sequence of operations that has been assigned an elementary operation class. Operations have attributes which cover the extension to classification scheme as discussed in Section 3.1.1. All possible profile elements and attributes are listed in Table 7.

In the program containing the for loop statement and the while loop statement, there also is judgment nodes, that is, the exit condition of the loop. Therefore, the for statement and the while statement should also be a structure feature information in the control flow. The analysis results of the for loop structure is respectively shown in Figure 3. Since the two codes implement exact same function, the intermediate code obtained by GCC is exactly same. The do while loop structure and the while loop structure are also the same.
