/* In a predator-prey simulation, you compute the populations of predators and prey,
using the following equations;
prevn+ 1 = preyn * (1 + A - B * predm)
predm+1 = predn * (1 - C + D à preyn)
preyn+ 1 and predn+ 1 are the just the next preyn and predn respectively.
This is not valid c++
Here, A is the rate at which prey birth exceeds natural death, B is the rate of predation,
C is the rate at which predator deaths exceed births without food,
and D represents predator increase in the presence of food.
Write a program that prompts users for these rates, the initial population sizes,
and the number of periods. Then print the populations for the given number of periods.
As inputs, try A = 0.1, B = C - 0,01, and D = 0.00002 with initial prey and
predator populations of 1,000 and 20.
The following is the sample run using the data above:
Rate at which prey birth exceeds natural death (A): 0.1
Rate of predation (B): 0.01
Rate at which predator deaths exceed births without food (C): 0.01
Predator increase in the presence of food (D): 0.00002
Initial prey population: 1000
Initial predator population: 20
Number of periods: 5
