strcat with char from array in c

Question

This may be a silly question, but I'm struggling to solve this problem. I know that to append a char to a string I can do something like this:

char c;
char string[10] = "";
strcat(string, &c);

Now, this works well for char variables, but the problem is that when I try to append a char from an array:

char array[5];
char string[10] = "";
strcat(string, &array[0]); //&array[0] returns the entire array, not just array[0]

Question: How can I append a single char from an array to a string?

first snippet doesn't work correctly. Also You can use strncat for one character addition. — BLUEPIXY

strcat requires a null-terminated string for its second argument. — Tom Karzes

The first part doesn't work either. Try this instead stackoverflow.com/a/7853834/597607 — Bo Persson

You can use strncat().Here length is the number of characters you want to append to string

strncat(string, array, length);

For appending single character, use length = 1
