Question

C++ exercise:

Lottery Number Generator

Design a program that generates a 7-digit lottery number. The program should have an Integer array with 7 elements. Write a loop that steps through the array, randomly generating a number in the range of 0 through 9 for each element. (Use the random function that was discussed in Chapter 6.) Then write another loop that displays the contents of the array.
