C++:声明一个带有函数的类,它处理字符串

#include <iostream>
#include <string>

class StringHandler {
private:
    std::string str;

public:
    StringHandler(const std::string& s) : str(s) {}

    void printString() {
        std::cout << "String: " << str << std::endl;
    }

    int getStringLength() {
        return str.length();
    }

    std::string reverseString() {
        std::string reversedStr(str);
        std::reverse(reversedStr.begin(), reversedStr.end());
        return reversedStr;
    }
};

int main() {
    std::string inputStr;
    std::cout << "Enter a string: ";
    std::cin >> inputStr;

    StringHandler handler(inputStr);
    handler.printString();

    int length = handler.getStringLength();
    std::cout << "Length of the string: " << length << std::endl;

    std::string reversed = handler.reverseString();
    std::cout << "Reversed string: " << reversed << std::endl;

    return 0;
}
