Profiling with gprof

1. Compile with -pg option
2. Link with -pg and -g options
3. Run the program as usual. The binary gmon.out file will be generated.
4. To analyse the results run gprof
   

   $ gprof program-name [ data-file ] [ > output-file ]

If you don't specify the name of a data file, gmon.out is assumed.
