C programing:

Write a program to take two numerical lists of the same length ended by a sentinel value and store the lists in arrays x and y, each of which has 20 elements. Let n be the actual number of data values in each list. Store the product of corresponding elements of x and y in a third array, z, also of size 20. Display the arrays x, y, and z in a three-column table. Then compute and display the square root of the sum of the items in z.

Note: Sqrt should be rounded to 2 digits.

SAMPLE RUN:

Enter x file name: dat1

Enter y file name: dat2
