The program takes two command line arguments, the name of an input file that contains a set of integers and an integer.

If the input file does not exist then print an error message and exit the program.

If the file exists, then it is guaranteed to only contain valid integers.

Your program should split this input file into two separate files, one (named less.txt) containing

integers that are less than the threshold value specified on the command line, and one (named more.txt) containing the integers that are greater than the threshold value.

Both your output files, less.txt and more.txt, should print one number per line.

Note that you do not write any occurrences of the threshold value itself to either file.

./a.out myData 100 ./a.out noSuchFile 0  

The file specified, noSuchFile, does not exist
