Strings

What are ... ?

Strings are objects that let you store alphanumeric strings like names, addresses and text in general.

Why do we ... ?

We need strings to represent non-numeric data.

How do we?

Use the class string

• Microsoft Visual C++ 5 and above:
  • #include <string>
  • use namespace std;
• Older versions of Borland:
  • #include "francastring.h"
• Borland version 5
  • #include  <cstring>

In any event, please use:

#include "franca2001.h" instead of "franca.h"

Declare String objects

string name,address;

What can we do?

• input/output
• assignment
• comparison
• concatenation

Other operations:

• Find length of string, locate a substring inside the string, etc.
• Those operations are NOT available with francastring.h.
