This program should get names of input and output files from command line (NOT from user input) read in integers from a csv (comma-separated values) file into a vector compute the integer average of all of the values convert each value in the vector to the difference between the original value and the average write the new values into a csv file

1. write a statement that declares a string variable named city. the variable should be initialized so it references an object with the string “san francisco”. a) assume that stringlength is an int variable. write a statement that stores the length of the string referenced by the city variable (declared in question1) in stringlength. b) assume that onechar is a char variable. write a statement that stores the first char- acter in the string referenced by the city variable (declared in question1) in onechar. c) assume that uppercity is a string reference variable. write a statement that stores the uppercase equivalent of the string referenced by the city variable (declared in question 1) in uppercity. d) assume that lowercity is a string reference variable. write a statement that stores the lowercase equivalent of the string referenced by the city variable (declared in question 1) in lowercity.
