swap是库里面实现的一个函数(交换两个string类类型对象)。 void test8(){string s1("hello world");string s2("I Love you");cout << "s1: " << s1 << endl;cout << "s2: " << s2 << endl;s1.swap(s2);cout << "s1: " << s1 << endl;cout << "s2: " << s2 << endl;} 3.4...
然后swap(tmp)就是让s2和tmp进行交换,因为this指针是s2 原因是string(const string& s)这个拷贝构造函数中的this指针就是s2,所以函数里面的this指针也默认是s2,交换后因为s2一开始就是指向的空,所以交换后tmp也指向空,而s2就指向tmp开出来的新空间 因为tmp是一个局部对象,出了作用域后就会调用析构函数销毁 现在...
void swap(string &s2); //交换当前字符串与s2的值 7、string类的查找函数: int find(char c, int pos = 0) const;//从pos开始查找字符c在当前字符串的位置 int find(const char *s,int pos = 0) const;//从pos开始查找字符串s在当前串中的位置 int find(const char *s, int pos, int n) co...
String function are the functions that are used to perform operations on a string. C++ uses <string.h> library to provides various string functions like strcat, strlen, strcmp, strcpy, swap, and many more where strcat is used to concatenate string, strlen will calculate the length of the str...

In C++, bubble sort is one of the easiest sorting techniques. In this sorting technique, the strings are sorted by comparing the adjacent strings or characters in the string and swap them according to the specified order that can be alphabetically in the case of strings in C++. ...
