Thread: [C/C++] Conversion of files

Hello to all

I tried to schedule something in Batch but I was advised a language somewhat more complete for that,here's what I do:

- Create a. Txt file for each file. Csv present in the folder where the program is located by running the following changes:

xxx.csv (consisting of two columns of numbers separated by tab)

1 0
2 0.1
3 0.2
4 0.3
5 0.5
6 0.7
... ...

in this file xxx.txt

n
0
0.1
0.2
0.3
0.5
0.7
...

where n represents the number of lines in the file xxx.txt (minus line n of course)

Could you help me?

Thank you in advance

In C, use fopen, fgets or fread, fprintf or fwrite, and fclose.

In script:
xxx.csv wc-l | cut-f 1-d ''> xxx.txt; awk '(print $ 2)' <xxx.csv>> xxx.txt
