insert image using set atribute

To insert an image using the set attribute in C++, follow these steps:

1. Include the necessary header files:
2. #include <iostream> for basic input/output operations.
3. #include <fstream> for file input/output operations.
4. #include <string> for working with strings.

5. #include <sstream> for working with string streams.

6. Declare the necessary variables:

7. std::ofstream file to create a file object.
8. std::stringstream data to store the image data.
9. std::string image to store the file name of the image.

10. std::string line to read each line of the file.

11. Open the image file:

12. Use file.open(image, std::ios::binary) to open the image file in binary mode.

13. Check if the file is open:

14. Use if (file.is_open()) to check if the file is successfully opened.

15. Read the image data:

16. Use while (std::getline(file, line)) to read each line of the image file.

17. Use data << line to store the image data in the data stringstream.

18. Close the image file:

19. Use file.close() to close the image file.

20. Set the image attribute:

21. Use setAttribute("src", "data:image/jpeg;base64," + data.str()) to set the image attribute. Replace "image/jpeg" with the appropriate format if the image is in a different format.

22. Output the HTML code:

23. Use std::cout to output the HTML code containing the image attribute.

Here is an example code snippet that demonstrates inserting an image using the set attribute in C++:

#include <iostream>
#include <fstream>
#include <string>
#include <sstream>

int main() {
    std::ofstream file;
    std::stringstream data;
    std::string image, line;

    image = "image.jpg";
    file.open(image, std::ios::binary);

    if (file.is_open()) {
        while (std::getline(file, line)) {
            data << line;
        }
        file.close();

        std::cout << "<img src=\"data:image/jpeg;base64," << data.str() << "\">" << std::endl;
    }

    return 0;
}

Note: Replace "image.jpg" with the actual file name and path of the image you want to insert.
