C/C++ Code/Program For Cattle Food Business Planner

 /*The following C++ Code will ask for the daily consumption of the monkey 1,2 & 3. And Display A record of average consumption made by them in a week. And display which day it was minimum or maximum or who has eaten maximum or minimum. Thus this C++ Code / Program helps to Plan The Daily Consumption of the cattle fodder & thus act as a Cattle Business Planner*/
