C + + STL string

Initialization

Function prototypes	Function
String ()	To create an empty string
String(const string& str)	Initializes another string object with one string object
String(const Char* s)	Class with C-style string s
string (int n, char c)	class with n characters c.

Assign Value

Function prototypes	Function
String& operator= (const Char* s)	char* type string assignment to the current string
string& operator= (const string &s)	Assigns the C-style string s to the current string
String& operator= (char c)	The character assigned value to the current string
String& Assign (const char *s)	assigns the string s to the current string
String& Assign (const char *s, int n)	Assigned the first n characters of the string s to the current string
String& Assign (const string &s)	Assigns the string s to the current string
String& Assign (int n, char c)	assigns the current string with n characters c
String& Assign (const string &s, int start, int n)	start s n characters assigned value from Start to string

Access character

Function prototypes	Function
Char& operator[] (int n)	Use [] method to take character, no subscript check
Char& at (int n)	Using the at method to obtain the character, there will be subscript legality check

Stitching

Function prototypes	Function
String& operator+ = (const string& str)	Overloaded + = operator
String& operator+ = (const char* str)	Overloaded + = operator
String& operator+ = (const char c)	Overloaded + = operator
String& Append (const char *s)	Concatenate the string s to the end of the current string
String& Append (const char *s, int n)	Connect prompt the first n characters of the string s to the end of the current string
String& Append (const string &s)	With operator+= ()
String& Append (const string &s, int pos, int n)	Connect prompt the n characters from the POS in the string s to the end of the current string
String& Append (int n, char c)	Adds n characters to the end of the current string C

Find and replace

Function prototypes	Function
int Find (const string& str, int pos = 0) const	Find the first occurrence of Str , start from POS
int Find (const Char* s, int pos = 0) const	Find The first occurrence of S , start from POS
int Find (const Char* s, int pos, int n) const /c4>	Find The first n characters of S from the pos position position
int Find (const char c, int pos = 0) const /c16>	Find character c first occurrence position
int rfind (const string& str, int pos = NPOs) const	Find the last location of str and find it from POS
int rfind (const Char* s, int pos = NPOs) const	Find the last occurrence of S , starting from Pos
int rfind (const Char* s, int pos, int n) const	Find the first n characters of S from Pos last position
int rfind (const char c, int pos = 0) const	Find character c last occurrence position
String& Replace (int pos, int n, const string& str)	Replace n characters from Pos starting with a string str
String& Replace (int pos, int n, const Char* s)	Replace n characters starting with Pos As String s

Comparison

Function prototypes	Function
int Compare (const string &s) const	Compare to string s
int Compare (const char *s) const	Compare to string s

Sub-string

Function prototypes	Function
String substr (int pos = 0, int n = npos) const	Returns a string of n characters starting with the POS

inserting and deleting

Function prototypes	Function
String& Insert (int pos, const Char* s)	Insert C-style string s before POS location
String& Insert (int pos, const string& str)	Insert string in front of POS location str
String& Insert (int pos, int N, char c)	Insert n characters before POS position C
String& Erase (int pos, int n = npos)	Delete n characters starting at POS location
