The elements of an array can be of any data type, including arrays! An array of arrays is called a multidimensional array. int array[3][5]; // a 3-element array of 5-element arrays Since we have 2 subscripts, this is a two-dimensional array. In a two-dimensional array, it is convenient to think …
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. Tell the compiler where to look for the header file(s) …
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 …
Consider the case where we want to find the average test score of a class of students. Using individual variables: int numStudents{ 5 }; int score0{ 84 }; int score1{ 92 }; int score2{ 76 }; int score3{ 81 }; int score4{ 56 }; int totalScore{ score0 + score1 + …

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 …
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 are not initialized when created. One way to “initialize” an array is to do it element by element: int prime[5]; // hold the …
Note: This chapter is a bit harder than the previous ones. If you feel a little discouraged, stick with it. The best stuff is yet to come! In lesson , you learned that you can use a struct to aggregate many different data types into one identifier. This is great …
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 control flow statements as well. The causes a while loop, do-while loop, for loop, or switch statement to end, with execution continuing …
By far, the most utilized loop statement in C++ is the for statement. The (also called a ) is preferred when we have an obvious loop variable because it lets us easily and concisely define, initialize, test, and change the value of loop variables. As of C++11, there are two …
