Write C++ program in .cpp file and algorithm in .doc 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 largest, second and third largest of the random numbers and their array position
5. Delete all the elements of the array having values between 20-40 and print the residual array
6. Sort the residual data in the array in an ascending order and print
7. Insert elements 50 and 80 in the sorted array at their respective positions and print the final array
