Programming new fag here
Hoping you guys will help me out, just doing some homework for software design. I need a flowchart or pseudo-code for this question:

Create an algorithm using either a flowchart or psuedocode to enable the owner of a video hire shop to select from the following routines:
1. Create a new customer
2. Enter customer details
3. See all videos for hire
4. Hire a video
5. Send letters to customers

I am stuck so help would be awesome

display video hire shop system
display 1. Create a new customer
2. Enter customer details
3. See all videos for hire
4. Hire a video
5. Send letters to customers
input system_selection
if system_selection == 1 then new_customer
if system_selection == 2 then enter_customer_details
if system_selection == 3 then display videos for hire
if system_selection == 4 then hire a video
if system_selection == 5 then send letter to customers
