In this program you will write a C++program to analyze a small subset of the data that has been collected.See file cityCensus.txt .Use precisely fiveparallel arrays: oneforname of city, one for total population, one for average age of residents, one for number of households,and one for the average number ofpeople per household.Note that the average number of people per household is not read in but it is calculated by dividing the total population by the number of households.Assume a maximum of 100cities.An output file is opened in main() and remains open until the end of the execution.Input:Write a functionto input the name of each city, the total population, the average age of residents, and the number of households.Repeat until end of file. Use getline(file, string name) to input text with spaces. You will find a very mischievous character to deal with both after the name of the cityand at the end of the five numericalvalues. You will enjoy knowing about file.ignore(). You may do the calculation of the average number of people per household as you are reading the input and store this value in the fifth array.Output:Write a separate function to output to the file all city census informationwith name of city, total population, average age, and average number of people per household. NOTE THAT THE NUMBER OF HOUSEHOLDS IS NOT BEING OUTPUT.Processing: Call the output function to outputto a fileall data in the original order.Write a separate function to compute and return the average population for all cities. Do not output from this function but return the valueand print it out to the screenfrom main().Write one and only one function to return the subscript of the citywith the highest average age. There is no output in this function. Do not assume a sorted array. In main(),the name(s) of the cities with the highest average age is to be output to the screen.Extra credit will be given for covering the possibility of multiple cities with same highest age. Use a selection sort to sort citiesby populationin descending order. This is written as a separate function with no output.Write the sorted array to the file.Write a function to prompt the user for the name of a city. Output to the filefrom this functionthe population, average age, and average number of people per household or output message No such cityin the list.THEME ISSUES:one-dimensional arrays,if statements, file input,file output, searching, sortingAbsolutelyno two-dimensional arrays, no structures and no menu function.Sample output before sorting:
