e. Add a prompt to ask the user to input their last name (no spaces ; please use underscores if needed), age and a balance of their choice. Create a new entry in the patient_list array with this information [Important note: you can statically modify the code to have the patient_list array hold an extra entry ; no need to do any dynamic memory allocation to accommodate the new entry]
