How do I compare strings in C++?

How do I compare strings in C++?

In C++, you can compare strings using the == operator, the compare() method, or the strcmp() function.

Can you show me an example using the compare() method?

Sure! Here's a simple example:

#include <iostream>
#include <string>

int main() {
    std::string str1 = "Hello";
    std::string str2 = "World";
    if (str1.compare(str2) == 0) {
        std::cout << "Strings are equal.";
    } else {
        std::cout << "Strings are not equal.";
    }
    return 0;
}

What about using strcmp()? Is it different?

Yes, strcmp() is a C-style string function. Here's how you can use it:

#include <iostream>
#include <cstring>

int main() {
    const char* str1 = "Hello";
    const char* str2 = "World";
    if (strcmp(str1, str2) == 0) {
        std::cout << "Strings are equal.";
    } else {
        std::cout << "Strings are not equal.";
    }
    return 0;
}
