Typedefs

allocator_type	A type that represents the allocator class for a string object.
const_iterator	A type that provides a random-access iterator that can access and read a const element in the string.
const_pointer	A type that provides a pointer to a const element in a string.
const_reference	A type that provides a reference to a const element stored in a string for reading and performing const operations.
const_reverse_iterator	A type that provides a random-access iterator that can read any const element in the string.
difference_type	A type that provides the difference between two iterators that refer to elements within the same string.
iterator	A type that provides a random-access iterator that can read or modify any element in a string.
npos	An unsigned integral value initialized to –1 that indicates either "not found" or "all remaining characters" when a search function fails.
pointer	A type that provides a pointer to a character element in a string or character array.
reference	A type that provides a reference to an element stored in a string.
reverse_iterator	A type that provides a random-access iterator that can read or modify an element in a reversed string.
size_type	An unsigned integral type for the number of elements in a string.
traits_type	A type for the character traits of the elements stored in a string.
value_type	A type that represents the type of characters stored in a string.

Member Functions

append	Adds characters to the end of a string.
assign	Assigns new character values to the contents of a string.
at	Returns a reference to the element at a specified location in the string.
basic_string	Constructs a string that is empty or initialized by specific characters or that is a copy of all or part of some other string object or C-string.
begin	Returns an iterator addressing the first element in the string.
c_str	Converts the contents of a string as a C-style, null-terminated, string.
capacity	Returns the largest number of elements that could be stored in a string without increasing the memory allocation of the string.
clear	Erases all elements of a string.
compare	Compares a string with a specified string to determine if the two strings are equal or if one is lexicographically less than the other.
copy	Copies at most a specified number of characters from an indexed position in a source string to a target character array.
data	Converts the contents of a string into an array of characters.
empty	Tests whether the string is contains characters or not.
end	Returns an iterator that addresses the location succeeding the last element in a string.
erase	Removes an element or a range of elements in a string from specified positions.
find	Searches a string in a forward direction for the first occurrence of a substring that matches a specified sequence of characters.
find_first_not_of	Searches through a string for the first character that is not any element of a specified string.
find_first_of	Searches through a string for the first character that matches any element of a specified string.
find_last_not_of	Searches through a string for the last character that is not any element of a specified string.
find_last_of	Searches through a string for the last character that is an element of a specified string.
get_allocator	Returns a copy of the allocator object used to construct the string.
insert	Inserts an element or a number of elements or a range of elements into the string at a specified position.
length	Returns the current number of elements in a string.
max_size	Returns the maximum number of characters a string could contain.
push_back	Adds an element to the end of the string.
rbegin	Returns an iterator to the first element in a reversed string.
rend	Returns an iterator that points just beyond the last element in a reversed string.
replace	Replaces elements in a string at a specified position with specified characters or characters copied from other ranges or strings or C-strings.
reserve	Sets the capacity of the string to a number at least as great as a specified number.
resize	Specifies a new size for a string, appending or erasing elements as required.
rfind	Searches a string in a backward direction for the first occurrence of a substring that matches a specified sequence of characters.
size	Returns the current number of elements in a string.
substr	Copies a substring of at most some number of characters from a string beginning from a specified position.
swap	Exchange the contents of two strings.

Operators

operator+=	Appends characters to a string.
operator=	Assigns new character values to the contents of a string.
operator[]	Provides a reference to the character with a specified index in a string.
