it's already something on which you can operate with standard string functions, assuming that it ends with '\0' since it's a requirement: it needs to know when the string ends.

You can prepare the space of char[] by memsetting it with memset(string, 0, length).

Null terminate the string. That is, set the character after the last character in your string to zero.

It must be null-terminated. That's the only requirement. I presume you know how to do that.
