All names must be composed from some combination of letters, digits and underscores. A name cannot begin with a leading digit but it must contain at least one letter. The only symbols that can physically separate one name from another are the binary operator symbols and semi-colons. Note that whitespace characters are only of relevance when a name identifies a type:
int x; // int is a type, x is a name; whitespace is essential here
int y, z; // comma-separated list of names; all whitespace within the list is ignored
x = y + z; // binary operators '=' and '+' separate the names (all whitespace is ignored)
