title: In susan Benchmark, I am not able to print the value of variable I want?
body: <p>IN Susan benchmark:
  Input to the benchmark is : Image
  Output of the benchmark is :Image</p>
  
  <p>I inserted a few functions to perform a few calculations. I want to see their final value after successful run of benchmark. I used </p>
  
  <p><code>printf("countervalue %d",counter)</code>  and</p>
  
  <p><code>printf(stderr,"countervalue %d",counter)</code></p>
  
  <p>in program, but I couldn't see the output anywhere. While output image is fine. Please tell me how to explicitly print value of variable during run.</p>
