C/C++ convert int to char (ASCII value) : I am trying to convert an `int` to a `char` using ASCII value. the `int` is randomly generated between `97` and `122` (from a to z).

So my question is all about how to make a random number between 97 and 122 and how to convert this value to a char.
(before I was able to make it easily but it's been a while I didn't code in C/C++, so I don't remember well how it works)
