  In this program you will find the total number of eggs collected during Easter Egg Hunt Game, the average number of eggs per child and the number of children participated in the game.

  Write a program that reads a sequence of positive integers, first zero or negative terminates the input. Each positive integer represents the number of eggs collected by one child. The program finds and prints the total number of eggs collected during Easter Egg Hunt Game, the average number of eggs per child and the number of children participated in the game.

  • Balance below $50,000 and AT LEAST 5 debit card transactions per month - 0.07 (7%) per month
  • For all balances, if the number of debit card transactions is below 5 then the interest rate is 0.01 (1%) per month
  
  Write a program that reads an initial deposit first, and then for each month reads the number of debit card transactions. The program finds and prints the following information:
  1. The balance in the account at the end of EACH month
  2. The balance on the account at the end of FIRST year (12 month)
  3. Average interest per year.
