这个页面中 Member types是指成员类型 Member functions是指成员函数,也就是前面类和对象所指的六个默认成员函数,因为六个当中有两个不是很重要,所以这部分只有四个,而因为构造和拷贝构造都是构造,所以将他们归纳在一起 Iterators是迭代器,后面会讲 Capacity是容量,这个听起来很抽象,容量不知道是什么东西,举个例子,...
concatenate an object // of type basic_string with an object of C-syle string type string s1s3 = s1 + s3; cout << "The string concatenating s1 & s3 is: " << s1s3 << endl; // Third & fifth member functions: concatenate an object // of type basic_string with a character constan...
The template function executes the specialized member function left.swap(right) for strings, which guarantees constant complexity. Example C++ Copy // string_swap.cpp // compile with: /EHsc #include <string> #include <iostream> int main( ) { using namespace std; // Declaring an object of...
Characters may be appended to a string using the operator+= or the member functions append or push_back. operator+= appends single-argument values while the multiple-argument append member function allows a specific part of a string to be specified for adding. Example C++ Копирај ...
With normal functions, we callfunction(object). With member functions, we callobject.function(). Also note thatstd::string::length()returns an unsigned integral value (most likely of typesize_t). If you want to assign the length to anintvariable, you shouldstatic_castit to avoid compiler wa...
