Problem: Chapter 7, Programming Challenge 7

My problem is to do a variation on the above problem. I need to write the program using a vector. I need to declare an open vector of unknown size, then read numbers from the file numbers.txt (link to it is supplied in 7 Programming Challenge). Use the push_back function to add an element to the array. Use a size member function to determine the final size of the vector. Then I need to calculate the following data and display the following data like the other problem.

-The lowest number in the array

-The highest number in the array

-The total of the numbers in the array

-The average of the numbers in the array

A solution or guide would be greatly appreciated.
