In Germany, Nassi–Shneiderman diagrams were standardised in 1985 as DIN 66261. [5] They are still used in German introductions to programming, for example Böttcher and Kneißl's introduction to C, [6] Baeumle-Courth and Schmidt's introduction to C [7] and Kirch's introduction to C#. [8] Nassi–Shneiderman diagrams can also be used in ...
Here a whole switch expression can be used to return a value. There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive. In Java SE 13 the yield statement is introduced, and in Java SE 14 switch expressions become a standard language ...
first checks whether x is less than 5, which it is, so then the {loop body} is entered, where the printf function is run and x is incremented by 1. After completing all the statements in the loop body, the condition, (x < 5), is checked again, and the loop is executed again, this process repeating until the variable x has the value 5.
The structured program theorem, also called the Böhm–Jacopini theorem, [1] [2] is a result in programming language theory.It states that a class of control-flow graphs (historically called flowcharts in this context) can compute any computable function if it combines subprograms in only three specific ways (control structures).
A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
This example shows the systematic process that takes place whilst the algorithm is processed. The initial value of x is zero, but i, although defined, has not been assigned a value. Thus, its initial value is unknown. As we execute the program, line by line, the values of i and x change, reflecting each statement of the source code in execution ...

Here is his example, translated from COBOL into Java. The purpose of these two programs is to recognize groups of repeated records (lines) in a sorted file, and to produce an output file listing each record and the number of times that it occurs in the file. Here is the traditional, single-loop version of the program.
