MatLab Q) Use the file ‘xandypts.dat’ (bundled in the .zip file) whic contains x and y data points in the following format:

                        x 0 y 1

                        x 1.3 y 2.2

Write a script that will (1) use fopen to open the file and error-check to ensure it was opened; (2) use fscanf to read x and y; (3) compute the sum of x and the sum of y; (4) print out the sum of x and sum of y; (5) use fclose to close the file and print whether or not the file was successfully closed.

FILE is a structure defined in <stdio.h>. Files can be opened using the fopen() function. This function takes two arguments, the filename and...

    Use two files for this lab: your C program file, and a separate text file containing the integer data values to process. Use a while loop to read one data value each time until all values in the file have been read, and you should design your program so that your while loop can handle a file of any size. You may assume that there are no more than 50 data values in the file. Save each value read from...
