How do you save an array as a file with C?

To save an array as a file in C, you can use the fopen function to create or open a file, followed by fwrite to write the array data to the file. For example:

<code class="language-c">FILE *file = fopen("array.dat", "wb");
fwrite(array, sizeof(int), array_size, file); fclose(file);
</code>

Here, replace int with the appropriate data type and array_size with the number of elements in the array. Ensure to handle errors for file operations appropriately in a complete program.
