to int is allowed,...
clearing a char array c
... achieve this.
On the other hand, if you are choosing to view this as a C/C++ null terminated string, setting the first byte to 0 will effectively clear the string.

Is Ruby pass by reference or by value?
...value nor pass by reference, at least in the sense those terms are used in C++. "pass by object reference" might be a better way to describe what Ruby does. In the end though, the best bet might be not to put too much meaning on any of these terms, and just get a good understanding of the behavior t...
