this is the requirement
Up to 100 pit data entries can be held
concurrently in the laptop memory.
Entering new pit data:
1- The user selects 'd' or 'D' from the menu.
2- The user enters the pit location name.
3- The program prompts for entry of the time
for a stone to hit the pit bottom (measured
using a stopwatch). Several measures can be
taken in succession.
4- Only the last depth estimate is recorded to
memory as the user enter 'n' or 'N' when asked
whether to take another measure.
HOW DOES THE DATA GET STORED IN MEMORY?
