What do you mean by "present"? Just using the arithmetic of complex numbers, or some "fancy" presentation on screen?
Traditionally, imaginary part is indicated by imaginary unit denoted "i", not "j"...

Not necessarily: "In the disciplines of electrical engineering and control systems engineering, the imaginary unit is often denoted by j instead of i, because i is commonly used to denote electric current in these disciplines."
Wiki: http://en.wikipedia.org/wiki/Imaginary_unit
It may be the OP is from an engineering background.

I don't say necessarily, of course...

You can't represent complex numbers with the notation you've shown.
Just like you need the * to represent multiplication (e.g., instead of "3b" for "3 times b", you must use "3*b"), you will need a different notation for complex numbers.
The link that Richard provided (Solution 1) has the documentation of a standard implementation for complex numbers in c++.
This is what you'll need to use.
