How to empty a char array?

Question

Have an array of chars like char members[255]. How can I empty it completely without using a loop?

char members[255];

By "empty" I mean that if it had some values stored in it then it should not. For example if I do strcat then old value should not remain

members = "old value";

//empty it efficiently
strcat(members,"new"); // should return only new and not "old value new"

You can use the following instruction:

strcpy_s(members, "");
