Description
You are going to write a complete C program which implements the following functionality:
-
The program reads real numbers from a file. Determines the chunks according to a criteria. For each chunk, the average of the numbers is calculated. Chunks are listed in ascending order based on their average.
-
Input file contains a sequence of real numbers which are separated by whitespace. The whole sequence consists of chunks which are separated by three consecutive “zeros”.(A separator)
-Each line of the output file lists the numbers in chunks.
-
Code it so that it reads a text file named input.txt and writes to a text file named output.txt. (If you don’t follow this convention your grade will be 0.0)
Example
Contents of the input file:
12.432 23.5 344.6 11.85 0.0 0.0 0.0 2.5 8.2313 19.27 0.0 0.0 0.0 70.001 23.
64 13.62
Here, there are 3 chunks:
12.432 23.5 344.6 11.85
2.5 8.2313 19.27
70.001 23.64 13.62
Find averages of numbers in each chunk. Create a text file with chunks ordered as stacked lines based on the calculated average of each.
2.5 8.2313 19.27
13.62 23.64 70.001
11.85 12.432 23.5 344.6
Each line is a chunk. Row order is according to the average(the chunk with the smallest average is on the first row.)
Remarks:
-
Maximum length of the input sequence is 1000.
-
Minimum length of a chunk is 1.
-
If there is more than 3 consecutive “zeros” (i.e. 0.0 0.0 0.0 0.0 ..), the first three ones are considered a separator sequence and the rest are assumed to be included in the chunk following the separator sequence.

-
Sequence starts with a chunk.
-
If nothing follows the separator sequence, it is still a separator sequence and not included in any chunk.
-
You don’t have to do error checking on the input file. You can safely assume that you will be given a proper input file which doesn’t violate the described format.
Turn in:
A complete C program <assignment_2_name_id.c> which can be compiled using the following command:
gcc -std=c99 assignment_2_name_id.c -o assignment_2_name_id
Caution:
-
Read and apply “Assignment Submission Rules and Other Related Information” document which available on the class e-learning system.
-
You may or may not get partial credit depending on how you structured or documented your code.
