For using the string header first we must have include string header file as #include <string> and then we can include string header in the following ways in C++:

1)

string header = "--- Demonstrates Unformatted Input ---";

2)

string header("**** Counts words****\n"), prompt("Enter a text and terminate"
" with a period and return:"), line( 60, '-'), text;

apstring  is not standard C    in C    you d want to  include the  lt string gt  header

You want to include  lt string gt  and use std  string    include  lt string gt   include  lt iostream gt   int main         std  string s    a string       std  cout  lt  lt  s  lt  lt  std  endl      But what you really need to do is get an introductory level book  You aren t going to learn properly any other way  certainly not scrapping for information online

Sources telling you to use apstring h are materials for the Advanced Placement course in computer science  It describes a string class that you ll use through the course  and some of the exam questions may refer to it and expect you to be moderately familiar with it  Unless you re enrolled in that class or studying to take that exam  ignore those sources   Sources telling you to use string h are either not really talking about C    or are severely outdated  You should probably ignore them  too  That header is for the C functions for manipulating null-terminated arrays of characters  also known as C-style strings   In C    you should use the string header  Write  include  lt string gt  at the top of your file  When you declare a variable  the type is string  and it s in the std namespace  so its full name is std  string  You can avoid having to write the namespace portion of that name all the time by following the example of lots of introductory texts and saying using namespace std at the top of the C   source files  but generally not at the top of any header files you might write

Use this    include  lt  string gt

User · Answer

You shouldn t be using string h if you re coding in C    Strings in C   are of the std  string variety which is a lot easier to use than then old C-style  strings   Use    include  lt string gt    to get the correct information and something std  string s to declare one  The many wonderful ways you can use std  string can be seen here   If you have a look at the large number of questions on Stack Overflow regarding the use of C strings  you ll see why you should avoid them where possible  -
