1. Write C statements which tests to see if input file has opened the data file successfully. If not, print an error message and exit the program. 2. Write C code which will read a line of characters (terminated by a \n) from input_file into a character array called buffer. NULL terminate the buffer upon reading a \n. 3. Write a C program that will get 10 grades of the student from a file. Get the average of the three grades and check each grade if its passing or not. Passing grade is 70. Store all the passing grade to an output file, and store all the failing grades to another output file.
