i wrote this program and im wondering whats the error in it i want it to check the length and the validity of the telephone number but when i try to put an input lets say i put 4743838abfc it still says valid number for the output which is wrong so what should i modify in order for it to work properly passing the input should be by argc and argv i cannot using anything else
