Note that all the activity in the while loop is done within its control condition: cin.getline(name[count++],20) This call to the cin.getline() function reads the next line into name[count] and then increments count. The function returns nonzero (i.e., true ) if it was successful in reading a character string into name[count]. When the end-of-file is signalled (with <Control-D> or <Control-Z>), the cin.getline() function fails, so it returns 0 which stops the while loop. The body of this loop is empty, indicated by the line that contains nothing but a semicolon.

Code-39 Creation In Java

A more efficient way to store C-strings is to declare an array of pointers: char* name[4]; Here, each of the 4 components has type char* which means that each name[i] is a C-string. This declaration does not initially allocate any storage for C-string data. Instead, we need to store all the data in a buffer C-string. Then we can set each name[i] equal to the address of the first character of the corresponding name in the buffer. This is done in Example 8.11. This method is more efficient because each component of name[i] uses only as many bytes as are needed to store the C-string (plus storage for one pointer). The trade-off is that the input routine needs a sentinel to signal when the input is finished. EXAMPLE 8.11 A String Array

This program illustrates the use of the getline() function with the sentinel character '$'. It is nearly equivalent to that in Example 8.10. It reads a sequence of names, one per line, terminated by the sentinel '$'. Then it prints the names which are stored in the array name: int main() { char buffer[80]; cin.getline(buffer,80,'$'); char* name[4]; name[0] = buffer; int count = 0; for (char* p=buffer; *p != '\0'; p++) if (*p == '\n') { *p = '\0'; // end name[count] name[++count] = p+1; // begin next name } cout << "The names are:\n"; for (int i=0; i<count; i++) cout << "\t" << i << ". [" << name[i] << "]" << endl; }

C-STRINGS
The entire input is stored in buffer as the single C-string containing George Washington\nJohn Adams\nThomas Jefferson\n . The for loop then scans through buffer using the pointer p. Each time p finds the '\n' character, it terminates the C-string in name[count] by appending the NUL character '\0' to it. Then it increments the counter count and stores the address p+1 of the next character in name[count]. name The resulting array name looks like this: 0 George Washington Note that the extra bytes that padded the 1 John Adams ends of the names in Example 8.10 are not 2 Thomas Jefferson required here.
If the C-strings being stored are known at compile time, then the C-string array described above is quite a bit simpler to handle. Example 8.12 illustrates how to initialize a C-string array. EXAMPLE 8.12 Initializing a String Array
This program is nearly equivalent to those in the previous two examples. It initializes the C-string array name and then prints its contents: int main() { char* name[] = { "George Washington", "John Adams", "Thomas Jefferson" }; cout << "The names are:\n"; for (int i = 0; i < 3; i++) cout << "\t" << i << ". [" << name[i] << "]" << endl; } The names are: 0. [George Washington] 1. [John Adams] 2. [Thomas Jefferson] The storage of the data in the name array here is the same as in Example 8.11.
8.8 STANDARD C STRING FUNCTIONS The C header file <cstring>, also called the C-String Library, includes a family of functions that are very useful for manipulating C-strings. Example 8.13 illustrates the simplest of these functions, the C-string length function, which returns the length of the C-string passed to it. EXAMPLE 8.13 The strlen() Function
This program is a simple test driver for the strlen() function. The call strlen(s) simply returns the number of characters in s that precede the first occurrence of the NUL character '\0' #include <cstring> int main() { char s[] = "ABCDEFG"; cout << "strlen(" << s << ") = " << strlen(s) << endl; cout << "strlen(\"\") = " << strlen("") << endl; char buffer[80]; cout << "Enter string: "; cin >> buffer; cout << "strlen(" << buffer << ") = " << strlen(buffer) << endl; }
