判断两个字符串是否相等的表达方式

在大多数编程语言中，可以使用相等运算符“==”来判断两个字符串是否相等，例如：

Python:

str1 = "hello"
str2 = "hello"
if str1 == str2:
    print("The strings are equal")

Java:

String str1 = "hello";
String str2 = "hello";
if (str1.equals(str2)) {
    System.out.println("The strings are equal");
}

C++:

#include <iostream>
#include <string>
using namespace std;

int main() {
    string str1 = "hello";
    string str2 = "hello";
    if (str1 == str2) {
        cout << "The strings are equal" << endl;
    }
    return 0;
}
