Sorting an array is the process of arranging all of the elements in the array in a particular order. There are many different cases in which sorting an array can be useful. For example, your email program generally displays emails in order of time received, because more recent emails are …
In the introductory lesson for this chapter (), we introduced the scalability challenges that occur when we have many related individual variables. In this lesson, we’ll reintroduce the problem, and then discuss how arrays can help us elegantly solve problems such as these. The variable scalability challenge, revisited Consider the …
C++ is a complex language, full of subtle traps for the unwary. There is an almost infinite number of ways to screw things up. Fortunately, modern compilers are pretty good at detecting a large number of these cases and notifying the programmer via compile errors or warnings. Ultimately, any error …
By default, WordPress displays categories and archive listings in blog form — that is, by showing either excerpts or the entirety of the last N posts (dependent upon theme). While this is great for reading, it’s less than wonderful when searching for specific past entries. Category/Archive Indexing is a WordPress …
To recap the process needed to use a library: Once per library: Acquire the library. Download it from the website or via a package manager. Install the library. Unzip it to a directory or install it via a package manager. Once per project: Tell the compiler where to look for …
A few years ago, a friend of mine introduced me to a board game called Empire Builder. The player is in charge of a railroad and is competing against the other players, who are also running their own railroad lines. Given a limited supply of money, each player has to …
A library is a package of code that is meant to be reused by many programs. Typically, a C++ library comes in two pieces: A header file that defines the functionality the library is exposing (offering) to the programs using it. A precompiled binary that contains the implementation of that …
Warning This lesson has been deprecated and replaced with the updated lessons in the latter half of chapter 17 (starting with lesson ). This lesson continues the discussion of arrays that began in lesson . Initializing fixed arrays Array elements are treated just like normal variables, and as such, they …
Now that we’ve covered std::vector and std::array, we’ll complete our coverage of arrays by covering the last array type: C-style arrays. As mentioned in lesson , C-style arrays were inherited from the C language, and are built-in to the core language of C++ (unlike the rest of the array types, …
Although you have already seen the break statement in the context of switch statements (), it deserves a fuller treatment since it can be used with other types of control flow statements as well. The causes a while loop, do-while loop, for loop, or switch statement to end, with execution …
