Probably.
What did you try? With what do you have problems?

[M^2]

well its like this i have writen program that asks user to input even and odd integers and then add the even and odd integers seperatley and divide them by pi=3.14 and it should give the answer upto 3 decimal points...
i dont know how to set the width.....

You will need to include this to set width

#include <iomanip>

Then use setw (#)
