我们可以通过反向迭代器,对其逆向遍历;反向迭代器的类型为 string::reverse_iterator; 代码语言:javascript 代码运行次数:0 运行 AI代码解释 intmain(){strings1("hello world");string::reverse_iterator rit=s1.rbegin();while(rit!=s1.rend()){cout<<*rit<<" ";rit++;}} 2.5下标访问: 关于元素的访问,...
reverse(p.begin(), p.end()); //string 可以调用reverse函数,string的表现像一个vecor<char> str += p + ' '; } string ans(str.begin(), str.begin()+str.size()-1); return ans; } }; 我用到 stringstream的题目: 将输入的字符串指定单词替换为其他单词 例如: "I will find u" 将 'u...
#include<iostream> #include<string> using namespace std; int main() { string s("hello"); string::const_reverse_iterator rit = s.rbegin(); while (rit != s.rend()) { //*rit = 2; 会报错 cout << *rit << endl; *rit++; } return 0; } rit可以看作指针,由const修饰后,rit指向的...
