title: displaying % completed while executing in C
body: <p>I have a C program that is taking like 5 minutes to execute. So I was thinking if I can like show the percentage completed or any type of interaction for the user while executing, since a blinking cursor is a bit dull.
  I was thinking of displaying percentage but can I like erase somehow, eg if task 1 ended I put 25% then after task 2 ends the 25% becomes 50%?</p>
  
  <p>Give me your input on some good interactions
  cheers!=)</p>
