Question

Write an algorithm and create a flowchart which simulate the testing for cell phone PIN. If the user entered the correct pin code, display “Welcome to DLM Telecom”. The cell phone user will enter his pin code three times; if on third try he fails to enter the correct pin code, display “Invalid Pin Code”. Thereafter, the program will prompt the user to enter PUK secret code for three times also. If the user still fails to enter PUK code after three tries, display “SIM BLOCKED” (PIN= 0123 & PUK = 1234)
