I have a C programming question I need help with. I need to read in all of the inputs from this text file provided and then calculate the average.

The file is basically 100 lines of text that look like this:

The 19 is always the first number followed by 3 doubles per row, and all of the doubles are similar in size. I need a C program to read in a file that contains about 100 lines of text like I posted, and then calculate the average of all of the numbers in the file. I can fix the exact numbers so that it matches my file correctly, I just need the logical parts to be correct. Thank you!

19 -1.55371 7.86704 7.86704 19 -1.55371 -7.86704 -7.86704 19 1.55371 7.86704 -7.86704 19 1.55371 -7.86704 7.86704
