Problem Solving with Algorithms and Data Structures using C++ The PreTeXt Interactive Edition

In this section, we will review the programming language C++ and also provide some more detailed examples of the ideas from the previous section. If you are new to C++ or find that you need more information about any of the topics presented, we recommend that you consult a resource such as the C++ Reference or a C++ Tutorial. Our goal here is to reacquaint you with the C++ language and also reinforce some of the concepts that will be central to later chapters.

C++ is an object-oriented programming language. It has a powerful set of built-in data types and control constructs. Since C++ is a compiled language, all the code written in this language, when run, are translated to machine code by a program called the compiler.

The following is an example of C++ code that writes to the console:

//Outputs strings to command line.
#include <iostream>
using namespace std;

int main() {
    cout << "Welcome to Problem Solving with" << endl;
    cout << "Algorithms and Data Structures!" << endl;
    return  0;
}
