C++ language

Write a program that takes graduation rates (per 1000 of the population) for North, South, East, West and Central United States. Input the number from each of the regions in a function returning an int with the graduation rate to the main program. Also figure out which region has the highest graduation rate in another function and display the result from inside that particular function. So your function prototypes should be something like: int gradrate() void highestgrad(double n, double south, double east, double west, double central) So you are using gradrate to read in the value of 0 to 1000 to give it to the north, south, east, west or central variables like: north gradrate)1000.0
