What does (char *) x or (void *) z mean?

Question

I know char *x means a pointer to char, but I\'m confused about what (char*) x means.

Answer 1

Actually, char *x is a declaration. x is pointer to char.

If you already have a variable, such as x, you can cast it to a different type. In your case, (char*) x is redundant, since x already is a pointer to char. But you can cast it to int * or something else. Although, note, it's not safe, since an int is larger than a char.
