In c$++$

String dataFileName and double onionQuantity are read from input. Open dataFileName as an output file. If the file fails to open:

Use cout to output dataFileName followed by $"$: file$-$open operation failure" and a newline.

Terminate the program with $1$ as the return value without writing to the file.

Otherwise, write onionQuantity followed by "kilograms of onions" and a newline to the opened file.

Ex: If the input is note. txt $20\mathrm{.}5,$ then note.txt contains:

$20\mathrm{.}5$ kilograms of onions
