I'm working with C right now. And there's a problem. I don't know how to save a FILE in custom place. When I run *.exe file, it saves them where code is placed. So how to make it save FILEs where I want it to be?(I can input a path)
a FILE is actually a long type that addresses a path on your computer.
Whether you use linux, windows, etc, the common thing about the paths is the idea that there are relative paths or absolute paths.
From what I've understood you probably did use the relative path, and I can guess you didn't specified a path at all, but only the file name.
Notice that a file's name alone is placed relatively to the path of the program you are running.
To fix your problem you might want to give an absolute path (such as "/home/user/" on linux or "C:\Users\user" on windows [pay attention for the escaping backslash]).
You can do it by something like this:
FILE *output = fopen("/home/user/output.txt", "w");
(where "w" means writing permissions to the file at the given path).
Hope this answers your question.
I'm trying to create a fairly simple batch file to download a file from our ftp site and store it in a specific directory. I would like to be able to put the batch file in the path so I can call it from anywhere. Currently I have a line like the following:
curl -v -u %FTP_USER%:%FTP_PASS% -Q "TYPE I" -o %OUTPUT_PATH% "ftp://%FTP_HOST%/%JAR_FILE_NAME%"
What I've discovered is that no matter the value of the output path, the file is always written in the current directory, and any path seperators are converted to underscores in the file name. This happens no matter if I use a '\' or '/' and if I try to escape it with double slashes I just end up with two underscores. Quotes around things don't seem to help either.
My question is does the -o option allow for outputting to a folder other than current working dir? I guess I can have the next step in the script to be "move the file to its destination", but that seems really kludgey.
This sounds exactly like a regression (reported here) we unfortunately brought in curl 7.47.0. We hope to release an updated, fixed, version soon and in the mean time you can probably consider downgrading to an earlier version to work-around this annoying issue.
I have a problem described here (you can read it for better understanding). I need to write .bat file that change path.
For example:
While sending a command in cmd: cd ~
I want to go to %HOMEPATH%. In fact - I just want to replace ~ by %HOMEPATH% in every command which include directories.
How can I achieve it? I read here that I must to put path changing .bat file inside %PATH%. How to do it? And how to code that path changing function in Windows scripting language?
Any advice would be appreciated ;)
setx path %path%;path\to\folder\file\is\in
set ~=%homepath%
cd %~%
this should work... close enough?
I need to read file in my program so while providing path I want to give relative paths because all files to be opened will be in some folder within current folder.
I tried this:
FILE *f=fopen("./abc/p.txt","r")
abc is folder withing current folder, but fopen returns NULL. How to do this thing?
This comes from either one of those:
. or ./abc/ is not readable or traversable
./abc/p.txt is not readable
./abc/p.txt does not exist
./abc/p.txt is a broken link
Look at errno to know what's the real problem.
this will run:
FILE *f=fopen("...\\abc\\p.txt","r");
Whenever I compile my program, I get the error above.
If you have problems like that, first of all your TC folder put in to the C:..drive.
after completing installation open turbo c blue screen.
there is a OPTIONS > Directories ..in that you can see for option to set up path..
include directories..you can set path there now.. C:\TC\INCUDE
libraries Directories..you can set path there...C:\TC\LIB
if you want to store your output in BIN then you can set..C:\TC\BIN..otherwise you can set another path where you want to store your output..
Finally you can give OK and finished processes..
It will now work properly
Do this: Open your turboc2 folder you have tc.exe file inside, beside this file you find another file as named as ' tcinst.exe ' open it.
You will see the installation menu:
select as-- > Option > Directory > Include directory
Here you have to change the path of the directory to the path where your INCLUDE folder is located. Same way change the path to library directory also over restart your tc.exe.
Check if you have anything like those stdio.h file and other header files under INCLUDE folder and LIB folder. LIB contains some files. In my case, I had the same issue but both of these folder were blank.. good to know.
Steps:
Press: ALT + O + D (i.e. press ATL (keep pressed) and then O english character) and then D).
You'll see a popup window.
This window will have values for INCLUDE and LIB directories. The by default value for these two boxes in the popup window are: Drive leter where you installed TC... i.e. C:\ or D:\ or whatever followed by the path for INCLUDE and LIB folder. So, in my case,
INCLUDE box was set to: "C:\TC\INCLUDE" and LIB directory value box was set to: "C:\TC\LIB" (without quotes).
Steps to resolve:
Press ALT + C.
Set your current directory as C:\TC\BGI
Press ALT + O + D, and put ../INCLUDE and ../LIB in Include/Lib directory values.
and now... when you'll run your progress, you'll say thanks to me. I like the archduchess C fractal graphics that I'm running on DOS Turbo C right now. Lol.
Go to OPTIONS tab then select directories option then enter the particular path where your turbo c folder exists.
Enter the path in all the four message boxes and it would start working like it did in my case. I have TurboC3 and all the files were together in one common root folder.
Check your environment include path. The file is not in the locations pointed by that environment variable.
Well, I've been working backshift just spent about 6 hours trying to figure this out.
All of the above information led to this conclusion along with a single line in dos prompt screen, when I exited the editor, go to the dos prompt my C: drive is mounted.
I did a dir search and what I found was: the way in which I had mounted the C drive initially looked like this
mount c: /
and my dir did not list all files on the C drive only files within the turboc++ folder.
From that I had drawn the conclusion that my directories should look like:
c:\include
not
c:\turboc++\tc\include
or
c:\tc\include
The real problem was the nature in which I had mounted the drive.
Hope this helps someone.

Since you did not mention which version of Turbo C this method below will cover both v2 and v3.
Click on 'Options', 'Directories', enter the proper location for the Include and Lib directories.
On most systems, you'd have to be trying fairly hard not to find '<stdio.h>', to the point where the first reaction is "is <stdio.h> installed". So, I'd be looking to see if the file exists in a plausible location. If not, then your installation of Turbo C is broken; reinstall. If you can find it, then you will have to establish why the compiler is not searching for it in the right place - what are the compiler options you've specified and where is the compiler searching for its headers (and why isn't it searching where the header is).
Make sure the folder with the standard header files is in the projects path.
I don't know where this is in Turbo C, but I would think there's a way of doing this.
First check whether the folder name is right or wrong since while you copying to one folder from other accidently it takes other folder address eg it take C instead of F So from OPTION>DIRECTORY change the folder name
Just Re install the turbo C++ from your Computer and install again in the Directory C:\TC\ Folder.
Again The Problem exists ,then change the directory from FILE>>CHANGE DIRECTORY to C:\TC\BIN\
