Using null pointers to simplify code examples in C/C++

reduce the use of stack space memory and reduce the calculation overhead during runtime!

 print_char(
char* array[]);
//函数原形声明

)      
{      
    
char
* test[]={"abc","cde","fgh",NULL};
//这里添加一个NULL,表示不指向任何地址,值为0   
 
    print_char(test);    
    
cin
.get();    
}

 print_char(

(*array!=NULL)    
    {    
        
cout
    }
