Write x^3 as x*x*x

I use mathematica compute functions I need for some external coding. However I cant use terms like x^2+y^3 since my programming language needs this term written as x*x+y*y*y. I would love to copy and paste the results from mathematica so how do I convert these terms?

(Please feel free to edit the Tags of this question since I didnt have a clue what to use here)
