Assignment Ahead of an expected drought this winter, the National Weather Service would like you to write a program that records the rainfall totals for 5 California cities and calculates a some statistics on the data. They would like to use your program in their branch offices across the state, so it needs to be able to accept rainfall data for any 5 cities, specified by the user. Using values stored in arrays, write a program that does the following: 1. Prompts the user for the names of 5 California cities. You can use any 5 cities of your choosing. Here are some to help you get started: (note that some cities have spaces in their names, this should be allowed). 2. Prompts the user in a loop) to enter rainfall totals (in inches, as a decimal number) for each of the 5 cities. Validate the input so the rainfall must be re-entered if it is less than zero or greater than 100. 3. Using 3 value-returning functions, calculate the locations with the highest and lowest rainfall and the average rainfall across the 5 cities. 4. Output the 3 calculated values with a precision of 2 digits past the decimal point.
