What are some advanced string manipulation examples in C++?

In C++, you can use the std::string class for advanced string manipulation. For example, you can use methods like substr(), find(), and replace(). Would you like to see specific code examples?

Yes, please provide an example using substr() and find().

Sure! Here's an example:

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello, World!";
    std::string sub = str.substr(7, 5); // Extracts 'World'
    std::cout << "Substring: " << sub << std::endl;
    size_t pos = str.find("World"); // Finds position of 'World'
    std::cout << "Position of 'World': " << pos << std::endl;
    return 0;
}

This code extracts 'World' and finds its position in the string.

That's great! Can you explain how replace() works?

Certainly! The replace() method allows you to replace a portion of the string with another string. Here's an example:

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello, World!";
    str.replace(7, 5, "C++"); // Replaces 'World' with 'C++'
    std::cout << str << std::endl; // Outputs: Hello, C++!
    return 0;
}

This replaces 'World' with 'C++' in the original string.
