Write C++ program in .cpp file to create seven subroutines (functions) described in the following and call them in the main function

1. To generate 100 random numbers between 1-100 in a randomData.txt file
2. To read the 100 random numbers from randomData.txt and store them in an array
3. Print the data in the array
4. Find the smallest and the largest of the random numbers and their array position
5. Insert an element of value100 in the 51^th position of the array
6. Delete all the elements of the array having values between 50-80 and print the residual array
7. Sort the data in the final array(residual) in an ascending order and print
