![Lab01 (Count single digits)
Write a program that generates n random integers between 0 and 9 and displays the count for each number. (Hint: Use an array of ten integers, say count, to store the counts for the
number of Os, 1s, ..., 9s.)
A modular program is expected - use Methods. The program specifications are as below.
In the main() method, declare an int array of size 10, named cnums.
Implement a method fillCnums(int[] cnt) that initializes the array to zero.
Implement a method countDigits(int[] cnt, int n) that accepts the cnums array and an integer n. The method should generate n random numbers in the range of 0 to 9.
It should keep a count of how many times each number, 0 to 9; is generated in the array cnums.
Implement a method printCnums(int[] cnt) to print the cnums array. Note, print "time" or "times" - which ever is appropriate.
Use basic structured programming and procedural programming.
Write a main() method that declares the cnums array. Invokes the countDigits() method with n = 10 followed by invoking the printCnums(). Then invokes the
count Digits() method with n = 100 followed by printCnums(). And again, invokes the countDigits() method with n = 1000 followed by printCnums().
Make sure you invoke the fillCnums(int[] cnt) method at appropriate times. And write out the heading for each set, n = 10, 100, and 1000.
