C and C++ USES null Pointers to simplify code and improve efficiency

The way you write it here avoids the for loop, reduces the memory usage of the stack space and reduces the computational overhead at run time!

#include   iostream>      
#include   string>      
using   namespace   std;      

void   print_char(char*   array[]); // the function prototype declares      

void   main(void)          
{          
        char*   test[]={" abc cde ", ""," fgh ", NULL & # 125;; // here we add an NULL, which means that we do not point to any address, and the value is 0      
        print_char(test);      
        cin.get();      
}        

void   print_char(char*   array[])      
{      
        while(*array!=NULL)      
        {      
                cout
