Can some one please help me in converting a decimal number(ANSI equivalent of a char) to its correspoding char...?

Like::: 65 stands for A,66 stands for B

i have a pointer to array of int containing :

65,66,67,68
which stands for
A,B,C,D

Is there any function which can convert those dec to char in C language ?
P.s) I cannot use itoa() because my gcc compiler states that it is not defined even after i have included stdlib.h
