[C++GDK] C++ basics. - iSteve - 14.05.2016

Recently i found out that we are able to use c++ to write scripts for samp.
But i do not see anyone making tutorials on C++ here( maybe because there are a lot available outside samp forums).
Anyhow, here is my tutorial on the basics of C++ which we can further use to write samp codes in C++.

Follow the following GitHub topic to set yourself up to be ready to script

Starting a C++ program
the basic library needed to begin a C++ program is <iostream>.

This has to be written at the begenning of your code.

The next line you would like to add is using namespace std.

The line using namespace std; tells the compiler to use the std namespace.

Now, let us come to the main() function.
the int main() is the line where a program begins.

C++ uses the cout operation along with "<<" operator to display an output to the terminal.
To take an input we would use cin with ">>" operator.


Now let us write a simple c++ program to display Hello world on the screen.

PHP код:
#include <iostream>
using namespace std;
// main() is where program execution begins.
int main()
{
   cout << "Hello World";// prints Hello World
   return 0;
} 
Simple program to read and then output a variable.

PHP код:
#include <iostream>
using namespace std;
// main() is where program execution begins.
int main()
{
    char str[80];//create a string of size 80 to take input
       cout << "Enter a string\n"; // here \n is inputted to move the pointer to the newline, alternatively you can =use endl
    cin>>str;
    cout<<"You entered :"<<str<<endl;// here we use endl instead of "\n", basically they both do the same task.
   return 0;
}

so you are using c++ in pawn or..??

Instead of writing basic C++ tutorials here, I suggest you to implement C++ with SA-MP GDK. There are many C++ tutorials out there if you simply search over ****** to know the basics. You can also link what to refer on your SA-MP GDK tutorials to make it more easier. Because there's really quite a lot to know about C++ for writing gamemodes using SA-MP GDK and it's best you refer them than creating separate threads.
