very very basic for loop and if else if else

#include 
using namespace std;
int main()
{
int i;
for(i=0;i<=13;i++)
    {cout << "Hello world! "<< i <
..notice that by the time it leaves the 
for (){}
 loop it is 14 not 13
Want system pause?
system("PAUSE");

then you'll need:
#include 

					

An example of some preprocessor stuff:

#include 
#define __thing__ " amazing "
#define __func__(x,y) ((x)>(y)?(x):(y))
#define _FAT_
#define _Cars_
using namespace std;
int main()
{
     cout << "Hello world!"<< __thing__ <
