1. Prompts the user for the parameters of the model: a, B, 7, 8 o If a user inputs a negative value for any of these parameters, the program should immediately print an error message and exit. • Here is an example of how to use the exit() function 2. Prompts the user to enter the initial values of the populations ko, uo, representing thousands of individuals. o If a user inputs a negative value for the initial population for either kelp or urchins, the program should treat the population as zero. 3. The program should calculate and output the populations k₁, ₁. Outputs should be shown with precision 3 decimal places, representing the population in thousands. The population should never grow negative (treat negative populations as zero).

i need help with this code please part A

1. Prompts the user for the parameters of the model: a, ß, 7, 8 o If a user inputs a negative value for any of these parameters, the program should immediately print an error message and exit. • Here is an example of how to use the exit() function 2. Prompts the user to enter the initial values of the populations ko, uo, representing thousands of individuals. o If a user inputs a negative value for the initial population for either kelp or urchins, the program should treat the population as zero. 3. The program should calculate and output the populations k₁, u₁. Outputs should be shown with precision 3 decimal places, representing the population in thousands. The population should never grow negative (treat negative populations as zero). Sample Output Sample input/output behavior for Checkpoint A are provided below. Your program's spacing, spelling, capitalization, and punctuation will need to match the sample output EXACTLY for this project. Ex 1 Sample Input/Output Given inputs a, B, 7, 8, ko, uo as: 1.5 .001 .05 2.5 100 2 The program outputs ==> Bull Kelp and Purple Urchin Population Simulator <== Model Parameters Kelp growth rate: Kelp death rate:
