What is C++
C++ Standard Libraries
Properly written C++ programs have a particular structure. The syntax must be correct, or the compiler will generate error messages and not produce executable machine language. This chapter introduces C++ by providing some simple example programs and associated fundamental concepts. Most of the concepts presented in this chapter are valid in many other programming languages as well.
File: main.cpp
#include <iostream>
using namespace std;
int main() {
cout << "Hello C++ Programming";
return 0;
}
Variations of our simple program
#include <iostream>
using std::cout;
int main() {
cout << "This is a simple C++ program!\n";
}
The using directive in allows us to use a shorter name for the std::cout printing object. We can omit the std:: prefix and use the shorter name, cout. The name std stands for “standard,” and the std prefix indicates that cout is part of a collection of names called the standard namespace.
#include <iostream>
using namespace std;
int main() {
cout << "This is a simple C++ program!\n";
}
Template for simple C++ programs
std::cout definition from into our program. Depending on what we need our program to do, we may need additional #include directives.
Can I teach myself C++?
As you can consider to learn almost any programming language by yourself. C++ is one of the more complex language you can find.
