fscan | comprehensive intranet scanning tool , which is convenient

I am trying to compute the average after reading in the data from a text file of int type.The program compiles fine. clang -std=gnu11 -Weverything -g3 -pedantic -g3 -O3 -lm average_weight_of_elephant_seals.c -o average_weight_of_elephant_seals

Suppose I want to compute the average weight of 2000 seals,the expected output is 6838.848152 but I get 1710.566467.I have no idea how to make sense of GDB yet.

Could someone please point out where have I have gone wrong?

I'm reading some data from a file "test1.txt",everything is ok but when encounter the Enter(line break),it gives me the answer I don't want

code and file:

main.c:

well While I was writing the question I found this answer

which gives the following solution to make it skip that line fscanf(config_file, "%*[^\n]\n"); It worked But I don't really understand the whole thing yet for example why there is two NEWLINE characters in the pattern what each of them represent and if there's more to know about this patterns

the reference in the answer gives a brief explanation about what this characters mean But I would like a more complete explanation,

After some searching I didn't manage to put my hands on any complete reference on this characters So if someone can provide a reference to read from or something. would be appreciated

I have a scons project directory containing following files:

so here i got a function that scan the file that has a single name and there phone number like that "andy 12345678"and when the user search for the name andy it will find it and printf the answer,now i want it to be more complex lets say the file has a full name and their number like this "andy bob mike 12345678" now when i use the code it will print "andy bob"because it fscan first two name "andy" and "bob"so how can i change the code that it can scan full name separately an compare it with what use searched for and print the full name with number NOTE that the full name can be like that "andy bob"or "andy bob mike" or "andy"with there number

The scenario goes like this,

A medical center needs to store appointment details in a text file called appointment.dat.

It includes the Patient name and the Appointment type. The appointment types can either be 'Consulting', 'Scanning' or 'Testing'. Only the first letter is stored in the file.

The requirement is to,

1. Create the appointment.dat file
2. Get 5 patient details through keyboard input and write the data into the appointment.dat file under the given sample format.
