In some ways, C-strings behave like fundamental objects (i.e., integers and reals). For example, they can be output to cout in the same way. But C-strings are structured objects, composed of smaller pieces (characters). So many of the operations that are provided for fundamental objects, such as the assignment operator (=), the comparison operators (<, >, ==, <=, >=, and !=), and the arithmetic operators (+, etc.) are not available for C-strings. Some of the functions in the C String Library simulate these operations. In 12 we will learn how to write our own versions of these operations. The next example illustrates three other C-string functions. These are used to locate characters and substrings within a given C-string. EXAMPLE 8.14 The strchr(), strrchr(), and strstr() Functions

The call strchr(s, ' ') returns a pointer to the first occurrence of the blank character ' ' within the C-string s. The expression p - s computes the index (offset) 3 of this character within the C-string. (Remember that arrays used zero-based indexing, so the initial character 'T' has index 0.) Similarly, the character 's' first appears at index 6 in s. The call strrchr(s, ' ') returns a pointer to the last occurrence of the character 's' within the C-string s; this is s[17] . The call strstr(s, "is") returns a pointer to the first occurrence of the substring "is" within the C-string s ; this is at s[5]. The call strstr(s, "isi") returns the NULL pointer because "isi" does not occur anywhere within the C-string s.

There are two functions that simulate the assignment operator for C-strings: strcpy() and strncpy(). The call strcpy(s1,s2) copies C-string s2 into C-string s1. The call strncpy(s1,s2,n) copies the first n characters of C-string s2 into C-string s1. Both functions return s1. These are illustrated in the next two examples.

This program traces call strcpy(s1,s2): #include <cstring> #include <iostream> int main() { char s1[] = "ABCDEFG"; char s2[] = "XYZ"; cout << "Before strcpy(s1,s2):\n"; cout << "\ts1 = [" << s1 << "], length = " << strlen(s1) << endl; cout << "\ts2 = [" << s2 << "], length = " << strlen(s2) << endl; strcpy(s1,s2); cout << "After strcpy(s1,s2):\n"; cout << "\ts1 = [" << s1 << "], length = " << strlen(s1) << endl; cout << "\ts2 = [" << s2 << "], length = " << strlen(s2) << endl; } Before strcpy(s1,s2): s1 = [ABCDEFG], length = 7 A X s1 s1 s2 = [XYZ], length = 3 B Y C Z After strcpy(s1,s2): D E E s1 = [XYZ], length = 3 F F G G s2 = [XYZ], length = 3 After s2 is copied into s1, they are indistinguishstrcpy(s1,s2) able: both consist of the 3 characters XYZ. The effect of strcpy(s1,s2) can be visualized as shown at right. Since s2 has length 3, strcpy(s1,s2) X X s2 s2 Y Y copies 4 bytes (including the NUL character, shown Z Z as ), overwriting the first 4 characters of s1. This changes the length of s1 to 3. Note that strcpy(s1,s2) creates a duplicate of C-string s2. The resulting two copies are distinct C-strings. Changing one of these C-strings later would have no effect upon the other C-string.
EXAMPLE 8.16 The Function strncpy()
This program traces calls strncpy(s1,s2,n): int main() { char s1[] = "ABCDEFG"; char s2[] = "XYZ"; cout << "Before strncpy(s1,s2,2):\n"; cout << "\ts1 = [" << s1 << "], length cout << "\ts2 = [" << s2 << "], length strncpy(s1,s2,2); cout << "After strncpy(s1,s2,2):\n"; cout << "\ts1 = [" << s1 << "], length cout << "\ts2 = [" << s2 << "], length } Before strncpy(s1,s2,2): s1 = [ABCDEFG], length = 7 s2 = [XYZ], length = 3 After strncpy(s1,s2,2): s1 = [XYCDEFG], length = 7 s2 = [XYZ], length = 3
= " << strlen(s1) << endl; = " << strlen(s2) << endl;
