There is an implicit assumption that they are nullterminated, but this is usually left to the programmer to enforce.

Space for Cstrings is allocated automatically.

Cstrings are a proper type.

The function strcpy(str1, str2) copies the characters in str2 to str1 after first checking to make sure that str1 has enough allocated memory to receive them.

The function strlen(c) returns the number of characters allocated to c.

The function strcpy(str1, str2) copies the characters in str2 to str1 after first checking to make sure that str1 has enough allocated memory to receive them.
