Stopping a While Loop with '\0'

Question

I am having trouble with stopping a while loop when a char array reaches '\\0'. I understand that this is the always the last element of any char array and so I do not understand why the code below never ends the loop. Any help would is appreciated.

char randomString[] = "testSTRING";

int counter = 0;
while (randomString[counter] != '\0')
    cout << "test";

Answer 1

Try this:

char randomString[] = "testSTRING";

int counter = 0;

while (randomString[counter++] != '\0')`

    cout << "test";
