下面是一个简单的C++字符串运算符重载代码示例:

#include <iostream>
#include <string>

using namespace std;

class myString {
private:
    string str;
public:
    myString() {
        str = "";
    }

    myString(string s) {
        str = s;
    }

    myString operator+(myString& s) {
        myString result;
        result.str = str + s.str;
        return result;
    }

    bool operator==(myString& s) {
        if (str == s.str) {
            return true;
        }
        else {
            return false;
        }
    }

    bool operator!=(myString& s) {
        if (str != s.str) {
            return true;
        }
        else {
            return false;
        }
    }

    void print() {
        cout << str << endl;
    }
};

int main() {
    myString s1("Hello");
    myString s2("World");
    myString s3("Hello");

    myString s4 = s1 + s2;
    s4.print();

    if (s1 == s2) {
        cout << "s1 is equal to s2" << endl;
    }
    else {
        cout << "s1 is not equal to s2" << endl;
    }

    if (s1 == s3) {
        cout << "s1 is equal to s3" << endl;
    }
    else {
        cout << "s1 is not equal to s3" << endl;
    }

    if (s1 != s2) {
        cout << "s1 is not equal to s2" << endl;
    }
    else {
        cout << "s1 is equal to s2" << endl;
    }

    if (s1 != s3) {
        cout << "s1 is not equal to s3" << endl;
    }
    else {
        cout << "s1 is equal to s3" << endl;
    }

    return 0;
}

这个例子中,我们定义了一个名为myString的类,它包含一个私有成员变量str,代表字符串。我们重载了+==!=运算符,以便我们可以使用这些运算符对myString对象进行操作。

在主函数中,我们创建了三个myString对象s1s2s3,并对它们进行了一些运算符重载操作。最后输出了运算结果
