youtube to facebook link converter

To convert a YouTube link to a Facebook link using C++, you can follow these steps:

1. Include the necessary libraries: Start by including the required libraries for performing string operations in C++. You'll need the <iostream> and <string> libraries.

2. Take user input: Prompt the user to enter the YouTube link and store it in a variable. You can use the std::getline function to read the entire line of input, including any spaces.

3. Extract the video ID: Extract the video ID from the YouTube link. The video ID is the unique identifier for the YouTube video and is typically found after the v= parameter in the link. You can use string operations like find and substr to extract the video ID.

4. Construct the Facebook link: Once you have the video ID, you can construct the Facebook link by appending the video ID to the Facebook video URL. The Facebook video URL format is typically https://www.facebook.com/watch/?v=<video_id>.

5. Print the Facebook link: Finally, print the constructed Facebook link to the console or display it in any desired format.

Here's an example implementation of the above steps:

#include <iostream>
#include <string>

int main() {
    std::string youtubeLink;
    std::cout << "Enter the YouTube link: ";
    std::getline(std::cin, youtubeLink);

    // Extract video ID from YouTube link
    std::size_t idIndex = youtubeLink.find("v=");
    std::string videoID = youtubeLink.substr(idIndex + 2);

    // Construct Facebook link
    std::string facebookLink = "https://www.facebook.com/watch/?v=" + videoID;

    // Print the Facebook link
    std::cout << "Facebook link: " << facebookLink << std::endl;

    return 0;
}

This program prompts the user to enter the YouTube link, extracts the video ID, constructs the Facebook link, and then prints it to the console.
