How to display all marks and there occurances

icedabz (6)
Hey guys, I've created a code that teachers can use to enter a students mark, find the average, s.d and how many occurances a certain mark has been entered.
This site has helped me a lot and i just need one final solution. I'm clueless on how to attack this question. As seen below a CMD prompt allows me to enter a students mark, find the average, the s.d and occurances. What I want to add is, instead of 6 - Find occurances for a certain mark. I would like to display all marks at once with there occurances to their right. Help ?

As far as my undertanding of the question...you can easily implement it by checking the array indices and storing them in some other array...
that would serve the purpose i think....
