Hello,

i wan to do c++ program in ubuntu that able to write a summary on the directory example is

drwx-x John 4096
d-w--x John 14
lrwx-x John 2300

How to i use array to put per column into array then access them so i can generate a report so it will be like this

Summary
Total directories = 2 ( the number of d in front determine it)
total link files = 1 ( the number of l in front determine it)
Name of user = John
Total size = 6410 (the total size of last column)

for now is i using char to determine the directories and link file


this is what i done to find the directories and link, but i cant use char method to grab name and calculate total size...anyone can tell me any method to generate the report...ty for all help

There are several ways to retain the data:
1) You could keep an array of strings, each entry being a line from the file. Then you could have functions that would read the string to tell you information like:

2) You could define a structure that represents one of these entries and keep an array of these structures. Then, when you read a line from the file, fill the structure and append it to the array.


On a side note, your report really does not require you to retain any of the data. Each of those fields is a count that can be incremented when parsing a line, just like you did with "directory" in your example.

Also, it looks like one of your questions is about converting a char[] to an integer. See atoi().

I hope this helps. Please post more specific questions if you need more help.

Be more specific in your questions. Nobody will do the program for you!

Bye!
