Lecture Visual programming: Chapter 12 - Muhammad Bilal Zafar

This chapter presents the following content: Acceptance of Input strings by automata, deterministic finite automata, simulating a DFA, regular expressions to automata, conversion of an NFA to a DFA, simulation of an NFA, construction of RE to NFA. | LESSON 12 Overview of Previous Lesson(s) Over View 3 CLR Programming Common Language Runtime (CLR) is a programming, that manages the execution of programs, written in any of several supported languages, allowing them to share common object oriented classes written in any of the languages. Microsoft refers to this Common Language Runtime as a "managed execution environment”. Over View CLR Programming – Input: Console::ReadLine() Reads complete line of input as a string using the function. String^ line = Console::ReadLine(); The variable line is of type String^ and stores a reference to the string that results from executing the Console::ReadLine() function. Console::Read() This function can read a single character. char ch = Console::Read(); With the Read() function, you could read input data character by character, and then, analyze the characters read and convert the input to a corresponding numeric value. 4 Over View Console::ReadKey() This function returns the key that was . | LESSON 12 Overview of Previous Lesson(s) Over View 3 CLR Programming Common Language Runtime (CLR) is a programming, that manages the execution of programs, written in any of several supported languages, allowing them to share common object oriented classes written in any of the languages.

ConsoleKeyInfo keyPress = Console::ReadKey(true); 5 Over View Safe_cast: The safe_cast operation is for explicit casts in the CLR environment. double value1 = 10.5; double value2 = 15.5; int whole_number = safe_cast (value1) + safe_cast (value2); The last statement casts each of the values of type double to type int before adding them together and storing the result in whole_number 6 Over View 7 Over View. 8 Private Members:- Over View 9 Friends Function Functions outside the class that are able to access all the members of a class i.e private or public. They are defined using the keyword friend Either include the prototype of a friend function in the class definition, or you can include the whole function definition. friend double BoxSurface(Cbox aBox); Over View Constant Objects: When an object is declared as const, it can’t be modified. Values such as pi or .
