basic_string Members

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.

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.

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.

back

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.

cbegin

Returns a const iterator addressing the first element in the string.

cend

Returns a const iterator that addresses the location succeeding the last element in a 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. Deprecated. Use basic_string::_Copy_s instead.

crbegin

Returns a const iterator that addresses the first element in a reversed string.

crend

Returns a const iterator that addresses the location succeeding the last element in a reversed string.

_Copy_s

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 contains characters.

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 a specified position.

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.

front

Returns a reference to the first element in a 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.

pop_back

Erases the last element of the string.

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.

shrink_to_fit

Discards the excess capacity of the string.

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.

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.
