 // Listing 15.9 Using strncpy()
 #include <iostream>
 #include <string.h>

 int main()
 {
     const int MaxLength = 80;
     char String1[] = "No man is an island";
     char String2[MaxLength+1];

     strncpy(String2,String1,5);              // limited to 5 rather than MaxLength
     String2[strlen(String1)] = '\0'; // add a null to the end
     std::cout << "String1: " << String1 << std::endl;
     std::cout << "String2: " << String2 << std::endl;

// you should see how strncpy can limit the length that you copy to a smaller
// portion of the string. This can come in handy when you want to subset something
