Research C++, styles, and Qt four Cross-Platform DevelopmentMaster C++ and layout styles jointly, utilizing the world's top open resource framework for cross-platform improvement: Qt four. An creation to layout styles in C++ with Qt four is a whole educational and reference that assumes no prior wisdom of C, C++, items, or styles. you are going to stroll via each center idea, one step at a time, studying via an intensive selection of Qt 4.1-tested examples and routines. by the point you are performed, you may be developing multithreaded GUI functions that entry databases and control XML files--applications that run on structures together with home windows, Linux, Unix, and Mac OS X. better of all, you will be writing code that is effective, reusable, and chic. examine gadgets quick: periods, inheritance, polymorphism, and extra grasp robust layout styles notice effective high-level programming concepts utilizing libraries, generics, and boxes construct graphical purposes utilizing Qt widgets, types, and perspectives examine complicated thoughts starting from multithreading to reflective programming Use Qt's integrated sessions for gaining access to MySQL info contains a whole C++ language reference

What happens if you enter a name such as Curious George as your name? ■ What happens if you remove the following line? 10. qxd 8/4/06 9:36 AM Page 18 CHAPTER 1: C++ INTRODUCTION 18 ■ Replace the statement cin >> yourName; with the statement getline(cin, yourName); and try Curious George again. ■ Can you explain the differences in behavior between cin >> and getline()? 9. ■ Add some more questions to the program that require a variety of numerical and string answers, and test the results. 2. 5.
For example, &x returns the memory address of x. An object that holds the memory address of another object is called a pointer. We say that the pointer points to the object at the stored memory address. int* y = &x ; In this example, y points to the integer x. The asterisk * following the int indicates that y is a pointer to int. Here we have initialized the int pointer y to the address of the int variable x. One of the powerful features of pointers is that, subject to rules that we will explore shortly, it is possible for a pointer of one type to hold the address of an object of a different (but related) type.

C++ retains the key features that have made C such a popular and successful language: speed, efficiency, and a wide range of expressiveness that allows programming at many levels, from the lowest (such as direct operating system calls or bitwise operations) to the highest level (manipulating large complex objects or graphs of objects).
