WHAT IS C++ ?

C++ is a general-purpose programming language used to create computer programs. Anything from art applications, music players ,operating systems and even video games!

TOOLS YOU'LL NEED

---

• An IDE (Integrated development environment ) .I suggest using Visual Studio , it's easy to use and user friendly .

MAKING YOUR FIRST C++ PROGRAM

• A C++ Program is a collection of comands which tell the computer "do something" like this one :

---

#include <iostream>
using namespace std;
int main()
{
  cout << "Hello world!";
  return 0;
}

This code tells the computer to output "Hello world " when you execute it .

• Let's see what every line of code does :

---

>  #include <iostream>

• C++ need some headers to run propery . <iostream>is a header ,it defines the standard stream objects that inputs and outputs data .

• #includeTells the program to include the header , in our case to include <iostream>

using namespace std;

• in this code , using namespace std; tells the compiler to use standard namespaces , std comes from standard .

int main()
{
  cout << "Hello world!";
  return 0;
}

• { } curly brakets indicates the front and end of a function ( int main())

• main() is a function . All programs begins with the main function ,no matter the program .

• cout << "Hello world!"; is a statement . Statement are expresion that can produce effect . It's the chocolate in the cake , the water from cofee , the meat from your bones . In this case , this line will output "hello world " on your screen after you execute the program .

• return 0; this is the return statement .It's used to close, terminate the function .

This completes today lesson , remember i am learning as you read , so i may have done some mistakes . Follow for tomorow's next lesson . Have a great night . I will post the lessons under tag #codecamp .
