Date due: to Course instructor by by 115gpm Dec 2 Submit New Skills Practiced (Learning Goals) Problem solving and debugging. Arrays Sorting Use of filestream variables Functional decomposition Functions and parameter passing. INPUT FILE DESCRIPTION and low temperature readings Assume you are given an input file that contains the daily high for several months in Hypothetical City. The file will have the following format. For each month the file will contain, mixture of upper the name of the month (string) the name will be in a random and lower case letters maximum value of the number of temperature reading for the month (int the this number will be the number of days in the month high followed by the low temperature reading (in) for each day sample input for a month: 105 85 jUlY 5 101 89 105 93 100 85 102 81 PROGRAM DESCRIPTION Design a C++ program that will interactively prompt the user for the name of the input file and read it use an input filestream variable to open the file for reading all output should be displayed to the screen display your name, lecture section and assignment read and process the data for each month display the name of the month with the first letter capitalized and the remaining letters in lower case along with a descriptive label display the number of temperature readings given with label e determine and display the highest high and lowest low temperature readings (as the month determine and display the average high and average low temperatures (with 3 digits to the right of the decimal) for the month determine and display the median high and low temperatures (will require sorting the temperatures use bubblesort) median should be displayed as an integer if there are an odd number of data sets median should be displayed with 1 digit to the right of the decimal if there are an even number of data sets. determine and display the standard deviation of the high and low temperatures (with 3 digits to the right of the decimal) for the month http://web.cs.unlv.edu/leelcs135/assign05 cs135fa16.html 11/30/2016
