Verifying Results Using diff

Follow the steps below in order to verify whether your program generates expected results for a program. In the description below, public01.in represents the input associated with a test and public01.output the expected output. The diff utility is used to verify whether the correct output is generated.

• Store the output of your program in a file by executing
  
  a.out < public01.in >! myResults
  
  
• Compare your results against the expected results by executing
  
  diff -U 0 -b myResults public01.output
  
  The -U 0 -b options are used by the submit server. You can also try -Bwi.
  
  
• Make sure you remove result files (e.g., myResults above) once you have verified your results. If you have errors in your code, the file created via output redirection could be huge (e.g., you have an infinite loop) what will affect the grace cluster.
