Conversion char/integer/char

Hi !
I´m working on a program that implements the famus ceasar encryption, but i can´t manage to convert a character to an integer and back to a character again ( I want to substistute an char with another one three "steps" forward ( an a turns into d an so on)). I only want the conversion algorithm. Please help me, it´s driving me crazy....
