Combine code into a Single statement

I am supposed to write a single statement that will save Sara and George into a text file called cppdata.txt using fprintf() and both fname(sara) and lname(george) are left justified and fname has 21 spaces and lname has 31 spaces.

This is what I have so far:

Code:

fwrite(&cppdata.txt

Not much but that is why I am asking for help!

So you were told to use fprintf(), but you used fwrite()

How about
fprintf( fptr, "%20s%20s\n", "sara", "george" );

Also, add at least the rest of the parameters so we have something to go on.
