Help! I Need to read an array of numbers from a txt file with C!

Question

Hi I have an array of numbers with many lines (actually not knowing how many) in a text file. Each line contains 6 numbers. I have to slice/cut in pairs over each line containing the six numbers to apply a function which takes as arguments three vectors with dimension two, then printing the results for each line with the position of each line. I am not sure how to face this problem I can print the whole array but not sure what is the best way to do what I want to do (to pass the data as function's arguments). I am quite new at this language. Should I use fgets?Thanks in advance and sorry for my English!

Answer 1

So your text file has example

1 2 3 3 5 6
2 3 4 5 6 7

And you want to make arrays like

int number[3]]2] = {1, 2, 3, 4, 5, 6}

Which would be like

1 2
3 4
5, 6

So on and so forth?

Answer 2

Mm something like
V1[2]={1 2}
V2[2]={3 3}
V3[2]={3 5}

Use v1 v2 y v3 as arguments for my function then print the solutions and then save again the next values in v1 v2 and v3. Compute and print. I need to print for each line the function for each three pairs of numbers.

Here are some helpful suggestions to opening and reading the text.

Then parse the string into arrays you need.
