My professor is asking to set precision when extracting a value from a file. But unsure what he means

Notes

For data precision on stdout we use the code below:

cout.setf$(ios$::showpoint$)$;

cout.setf$(ios$::fixed$)$;

cout.precision$(2)$;

This will not have any effect on the files. So you'll have to use a similar code. Recall the similarity from

outputting to stdout $($cout $$ "Hello"; $)$ and a file $($outFile $$ "Hello"; $).$ So you will have to do something

similar:

outFile.setf$(ios$::showpoint$)$;

outFile.setf$(ios$::fixed$)$;

outFile.precision$(2)$;
