The example is for 4X4 keypad and not single key. If your keypad returns characters like '1', '2',... for keys 1,2,... you have to store the keys in a string array like keys[5]. If key[0] = '1', key[1] = '2', key[2] = '3', key[3] = '4' and you terminate the array with key[4] = '\0'. So, your key[5] will be equal to "1234".
