no that is so fundamentally wrong, i do not know how to begin.

(int) variable

means cast the variable to int no matter what it was before.

on the other hand, int(x), and this only exists in C++, AFAIK, means create 
a new integer with the initial value x.

in this case, you are not trying to intialize a new char out of x, but jsut 
use the value of x.

you definitely should use snprintf, however, instead of sprintf.
or better yet, use a C++ solution if you are working in C++.
