控制结构(Control Structures) 一个程序的语句往往并不仅限于线性顺序结构。在程序的执行过程中它可能被分成两支执行,可能重复某些语句,也可能根据一些判断结果而执行不同的语句。因此C++ 提供一些控制结构语句 (control structures) 来实现这些执行顺序。 为了介绍程序的执行顺序,我们需要先介绍一个新概念:语句块(block ...
Most control structures are not used ininteractive sessions, but rather when writing functions or longer expresisons Control Structures: if if(<condition>){ ## do something } else{ ## do something else } if(<condition1>){ ## do something }else if(<condition2>) { ## do something diffe...

I’m reading Kent Beck’sSmalltalk Best Practice Patternsand learning a lot about how control structures work in what’s probably the purest object-oriented language. For example,ifisn’t used to manage conditionals. In Smalltalk, since all things are objects, including booleans, you can just ...
In Starting Out with C++: From Control Structures through Objects, Gaddis covers control structures, functions, arrays, and pointers before objects and classes. As with all Gaddis texts, clear and easy-to-read code listings, concise and practical real-world examples, ...
Chapter 4. Blocks, Shadows, and Control StructuresNow that I have covered variables, constants, and built-in types, you are ready to look at programming logic and organization. I’ll start by explaining blocks and how they control when an identifier is available. Then I’ll present Go’s ...
all indirect calls in your code are analyzed to find every location that the code can reach when it runs correctly. This information is stored in extra structures in the headers of your binaries. The compiler also injects a check before every indirect call in your code that ensures the targe...
Starting Out with C++: From Control Structures through Objects covers control structures, functions, arrays, and pointers before objects and classes in Tony Gaddis's hallmark accessible, step-by-step presentation. His books help beginning students understand the important d...
