How to compare string content in C++?

In C++, you can compare the content of two strings using the == operator. For example:

std::string str1 = "hello";
std::string str2 = "world";

if (str1 == str2) {
    std::cout << "The strings are equal" << std::endl;
} else {
    std::cout << "The strings are not equal" << std::endl;
}

To check if two strings have the same content, you can use the == operator; to check if two strings have different content, you can use the != operator.
