Thank you everyone!!
I'm sorry forgetting to tell u that i'm running my c++ program on ubuntu.

How do I get the memory usage of my c++ program? Which instruction that i can put in my program and it can tell the size of memory that my program used?

Thank you

I have more fluently in writting Java but for this program my advisor need me to convert my program from java to c++. I've already done with c++ code and the result is correct and got the same result...
