Simplify code with null pointers for increased efficiency in C + +

In this case, you can avoid using a for loop, reduce stack space memory usage and reduce run-time computing overhead!

#include <iostream>
#include <string>
using namespace Std;
void Print_char (char* array[]);//function prototype declaration
void Main (void)
{
    char* test[]={"abc", "CDE", "FGH", null};//add a NULL here, indicating no address, value 0
     Print_char (test);
    Cin.get ();
}
void Print_char (char* array[])
{
    while (*array!=null)
     {
        cout<<*array++<<endl;
     }
}
