Here is the output from the same program that we ran in Example 10.5, but which now uses our explicitly defined assignment operator:

Bar Code Encoder In None
Using Barcode creator for Software Control to generate, create barcode image in Software applications.
This time, when the assignment mycar = yourcar executes, it actually replaces the mycar object with a duplicate of the yourcar object. And since this is a distinct duplicate, changing yourcar [ 61 to the letter "L" has no effect on the mycar object. In other words, when you sell me your Lexus ES300 and then buy a new Lexus LS300 for yourself, I still have my ES300 and you have your LS300. The effect of our own user-defined assignment operator can be seen in the following diagram:

Here the new operator allocates storage for a new string in memory for the mycar object. So when the 9 is changed to an L" in the yourcar object, it has no effect upon the mycar object.

EXAMPLE 10.7 Another Test of the Assignment Operator
#include main0 String tout -w tout << name = tout << name("Babbage"), creator("Stroustrup"); "name = [II -x name << I']\nll; "creator = ['I << creator << "]\n"; creator; // calls the assignment operator "name = ['I c< name c< "]\W; '5tring.h"
The output looks like this:
First it uses the third constructor to construct the two String objects name and creator, representing the C-strings "Babbage" and "Stroustrup". Then it uses the assignment operator to assign the String object creator to the String object name. Notice how the length of name is
The diagram on the next page illustrates the action of the assignment name = treat or. When the function operator= is invoked, it creates the local variables thi s and s. The this pointer points to the object name which owns the call, and s is a reference to the object creator. The function changes thi s - >l en to 10 and resets thi s - >bu f to a newly allocated string of 11 bytes into which s . bu f is copied using the s t rcpy ( ) function.
10.6 THE ADDITION OPERATOR
The addition operator + is a natural choice for the concatenation function in a String class. After all, concatenation means adding two strings together to form a new string. Here is the concatenation function for our String class:
String operator+(const String& sl, const String& s2) l String s(sl.len + s2.len); strcpy(s.buf, sl.buf); strcat(s.buf, s2.buf); return s; >
strcpy s. buf
First it constructs a new String object s of length sl . len + ~2 . len. Then it uses the ( > and strcat ( ) functions defined in the string. h header file to copy ~1. buf to and append ~2. buf to it.

A String CLASS
In this example, we first construct the String objects first and last. Then we concatenate first, blank, and last, andassigntheresulttothe String object name. We can visualize the execution of this test driver like this:

Thelengthofthenew String object name is firstden + temp.len +last.len = lO+l+ 6 = 17, where temp is the temporary String object that represents the C-string I II.
