Effects
|
|
========================================
|
|
|
|
| Equivalent to ``assign(str, 0, npos)``.

|
basic_string& assign(basic_string<T, N2, Traits> const& str, size_type pos, size_type n);

Requires
|
|
========================================
|
|
|
|
| ``pos <= str.size()``.
|
|
|
|
Effects
|
|
========================================
|
|
|
|
| Determines the effective length rlen of the string to assign as the smaller of n and ``str.size() - pos`` and calls ``assign(str.data() + pos, rlen)``.

Returns

|
========================================

|
|
| ``*this``.
|

Throws
|
|
========================================
|
|
|
|
| std::out_of_range if ``pos > str.size()``.

|
.. sourcecode:: c++

basic_string& assign(value_type const* s, size_type n);
|
|
|
|
Requires
|
|
========================================
|
|
|
|
| s points to an array of at least n elements of value_type.
|
|
|
|
Effects
|
|
========================================
|
|
|
|
| Replaces the string controlled by *this with a string of length n whose elements are a copy of those pointed to by s.
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| ``*this``.
|

Throws

========================================
|
