Write a program to input temperatures for any number of days and then output the average for just the even days. You must: Create a vector of doubles called temperatures. Use a loop to Prompt the user for temperatures. Add them to the vector. Have some way for the user to indicate when they want to stop entering temperatures. Use a second loop to find the sum of the temperatures on even days $($the even index temperatures are $0,2,4,6,$ etc.$).$ Print the average of the even day temperatures showing only two decimals of precision
