Thread: [Dev-C++] I´d like to know your hints about file manipulations

Dear users,

   I like this list because we can ask questions
regarding not only about Dev-cpp, like the one
that I present to you now.

   Consider the following restrictions:
   -only ANSI-C commands;
   -not C++;
   -for file manipulation, only the following
    commands: fopen(), fscanf(), fgets(),
              feof(), and fclose();

   Inside this scenario, people can easly work
read and write files containing integers and floating
point numbers. Situations like names, sex (male/female),
option (yes/no), etc, can be replaced by integer codes.

   My question is:
   What is your style to work with strings, i.e., names
for example: for a program that expects to read a name from
a file (with spaces, variable size, etc), do you previosly
indicate a fixed number of characters (40, for example) and
use fgets twice (to read the 40 characters and read the '\n')?

Thanks a lot in advance
André

I normally let fgets read full lines, and then perform any decoding of the
contents.

Then you have a number of options. Comma-separated. Semicolon-separated.
Tab-separated. Encoded inside quotation marks.

I normally use strchr() to process the lines I have read with fgets().
