I have a those variables:

filename = 'test.png'
max_resolution = '512x512'

can you write the code needed to make new_filename equal 'test+512x512.jpg'
Certainly! You can create the `new_filename` by extracting the filename without the file extension and then appending the `max_resolution` followed by .jpg. Here's the Python code to achieve this:

```python
filename = 'test.png'
max_resolution = '512x512'

# Extract the filename without the file extension
filename_without_extension = filename.split('.')[0]

# Create the new_filename by combining filename_without_extension, max_resolution, and '.jpg'
new_filename = f'{filename_without_extension}+{max_resolution}.jpg'

# Print the new_filename
print(new_filename)
```

When you run this code, it will generate `new_filename` as 'test+512x512.jpg'.
Excellent, thank you. Can you also show me how to do the same thing in Javascript and C++?
Certainly, here's the above Python code rewritten in JavaScript and C++:

**JavaScript:**
```javascript
const filename = 'test.png';
const maxResolution = '512x512';

// Extract the filename without the file extension
const filenameWithoutExtension = filename.split('.')[0];

// Create the newFilename by combining filenameWithoutExtension, maxResolution, and '.jpg'
const newFilename = `${filenameWithoutExtension}+${maxResolution}.jpg`;

// Print the newFilename
console.log(newFilename);
```

**C++:**
```cpp
#include <iostream>
#include <string>

int main() {
    std::string filename = test.png;
    std::string maxResolution = 512x512;

    // Extract the filename without the file extension
    size_t dotPosition = filename.find_last_of('.');
    std::string filenameWithoutExtension = filename.substr(0, dotPosition);

    // Create the newFilename by combining filenameWithoutExtension, maxResolution, and .jpg
    std::string newFilename = filenameWithoutExtension + + + maxResolution + .jpg;

    // Print the newFilename
    std::cout << newFilename << std::endl;

    return 0;
}
```

These code snippets perform the same operations as the original Python code to extract the filename without the extension and create a new filename by combining it with the maximum resolution and the file extension. They also print the new filename to the console.
Nice
