Write a program that reads a list of integers from the keyboard and creates thefollowing information.a. Finds and prints the sum and the average of the integersb. Finds and prints the largest and the smallest integerc. Prints a Boolean (true or false) if some of them are less than 20d. Prints a Boolean (true or false) if all of them are between 10 and 90The input data consist of a list of integers with a sentinel. The program mustprompt the user to enter the integers, one by one, and enter the sentinel whenthe end of the list has been reached. The prompt should look like the following: Enter the numbers with <return>(99999 to stop):The output should be formatted as shown below: The number of integers is: xxxThe sum of the integers is: xxxxThe average of the integers is: xxx.xxThe smallest integer is: xxxThe largest integer is: xxxAt least one number was < 20: <true or false>All numbers were ( 10 <= n >= 90): <true or false>
