tailieunhanh - Lecture Visual programming: Chapter 15 - Muhammad Bilal Zafar

The following will be discussed in this chapter: Computing nullable, firstpos, and lastpos; computing followups; converting a RE Directly to DFA; minimizing the number of states of DFA; trading time for space in DFA simulation; two dimensional table; terminologies. | LESSON 15 Overview of Previous Lesson(s) Over View In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically. VPLs may be further classified, according to the type and extent of visual expression used, into icon-based languages, form-based languages, and diagram languages. 3 Over View Problem Definition: The principal function of a box is to contain objects of one kind or another, so, in one word, the problem is packaging. Basic operations on CBox class include: Calculate the volume of a Cbox. Compare the volumes of two CBox objects. Compare the volume of a CBox object with a specified value, and vice versa. 4 Over View. Add two CBox objects to produce a new CBox object that will contain both the original objects. Multiply a CBox object by an integer (and vice versa). Determine how many CBox objects of a given size can be packed in another CBox object of a given size. Determine the . | LESSON 15 Overview of Previous Lesson(s) Over View In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically.

Determine the volume of space remaining in a CBox object after packing it with the maximum number of CBox objects of a given size. 5 Over View In first preference we start writing the code to use the CBox class and its overloaded operators, first we assemble the definition for the class into a coherent whole. In this project we used the visual facilities that Visual C++ 2008 / 2010 provides for creating and maintaining code for our classes. 6 Over View In our project we distributed the code among several files for the first time during this course. It is not a common practice with C++ applications generally, but with Windows programming, it is essential. The sheer volume of code involved in even the simplest program necessitates dividing it into workable chunks. There are basically two kinds of source code files in a Header Files Source Files 7 Over View 8 Over View Arrays in C++ / CLI In C++ / CLI programming arrays are different from the native C++ arrays. Memory for a CLR array is allocated on .
