Number of total employees: 7
Average salary: $54571.43One way to check if your output file is correct is to run the wc command to count
the number of bytes in the file:
$ wc input/infile1.dat input/infile2.dat outfile 2 8 70 input/infile1.dat 0 6 59 input/infile2.dat 2 14 129 outfile
This shows that the output file is 129 bytes, which is the sum of the number of bytes in the two input files (70 and 59).
Another way to test your output file is to try using it as input to another run of your program.
2. Run using output file as input
If you are correctly creating the binry output file, you should be able to use the output file from one run as input file to other runs:

3. Run using large files
Here is a run on two large files from `~newhall/public/cs44/lab01` showing just part of the output:
$ ./sortEmployees ~newhall/public/cs44/lab01/input300.dat ~newhall/public/cs44/lab01/input400.dat outfile
