Question

Working in the C language, please help:

For this project, you will write a C program that will simulate and animate an ecosystem populated by two types of creatures: doodlebugs and ants. In this assignment, doodlebugs are the predators and ants are the prey. As the simulation runs, you should usually see the doodlebug population and the ant population grow and shrink in a cyclic manner; however, the built-in randomness many cause one or both creatures to die out completely.
this is on a 20x20 grid, with 100 ants and 5 doodlebugs in the beginning, use a 2D array for these as well as pointers and functions
please help and comment, no C++, just C,
thank you
