Suppose there are two cpp programs and we want the user to put the complete path of the first cpp file into second cpp file while it(second file) is running and compile and show the output there, so how can this be done?
How can I take in a path name like "C:myfolderfile.txt" where the user enters exactly that? I've tried putting the arg into a string, then looping through the string to find the '\', but by that time it is too late as c++ considers the '' as a escape character.
Is this even possible? I've googled it and everyone just says to make the user input the path with double \ or with a /.
The code I've written is for your basic invoice class. The issue I'm having is that the program works fine for the first invoice, but when I add a second object the program skips over the part where the user types in a part description.
#include <iostream> #include <string> using namespace std; class Invoice { public: void setPartDescription( string description ) {
[Code] ....
I thought maybe the "string description" I have in main being shared by both invoice objects might be causing the issue but I couldn't manage to resolve it by tinkering. Again the code works fine for the first object, the second and so forth mess up. I've attached a file showing when the part description gets skipped over (and it doesn't just default to the first input, it gets left blank).
I've been trying to figure out how to implement a way to save this board state throughout a user's inputted path. At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). How to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need transferring the board state to change with using a vector to store the size based on user input. How to proceed, using a first search to solve the puzzle from the current board's state.

I wanted to make my program read the file "input.txt". I did it successfully, but now I want to get the full path of the file "input.txt". Is there any way to do it?
I am trying to iterate through a file path to extract the file name. since the . separating the name from the extension is a unique character, i thought i would reverse iterate from the . to the first separating directories. however, when trying to reference the memory location of the position of the . in the string, i am getting an i-value error:
for (std::string::reverse_iterator iter = &(songPath.find('.')); iter != songPath.rend(); ++iter) { if (*iter == '') break; else songName.push_back(*iter); }
I need to open a text file game_scores.txt and i can not figure out a way to.
#include <iostream> #include <string> #include <fstream> using namespace std; int main() {
[Code] ....
the code is used to read the text and take the first 4 pieces of info but i do not know how to do it. i have already created the text file and moved it into the source. i am using visual studios 2012. In 2010 the text file would show a relative path, it doesn't in 2012
I need to append file path for some particular program. But the problem is when I append it like below, it gets error whether filepath seems to be C:/Users/My/Desktop/C++/1.txt
int i=1; stringstream str; str<<"C:/Users/My/Desktop/C++/"<<i<<".txt"; string filepath=str.str(); cout<<filepath; ifstream ipf(filepath); if(ipf) { do some thing...}
But if it was like this no error, program work as desired.
int i=1; stringstream str; str<<"C:/Users/My/Desktop/C++/"<<i<<".txt"; string filepath=str.str(); cout<<filepath; ifstream ipf("C:/Users/My/Desktop/C++/1.txt"); if(ipf) { do some thing...}
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...
How it make it work for my project. Runtime means I am going to have to give the path at the command line?
Here is how I have to run it, so I can test it against the example inputs and outputs they give us to test our program. I am using putty. Already crated the folders inside my project folder, but don't know how to implement it on my source code.
I have an application which is used for calibration for electrical components. Here I want to set a rootpath for this application. I did some research and I found out that I can get the rootpath of the application (that is where the exe is stored) But what I am really looking for is once I start the application the root path should be what I assign. For instance currently the root path is "C:UsersPublicDocumentsABC.ToolsProjects" but I would like the root path to be "E:New ABC" Is this possible? I wrote some code where I call the exe of the application and it opens the file in a folder that I specify :
Compilation is success full ,but i am observing that some junk value is there in the path variable. After Reaching If statement cursor went to final return statement ...
I am trying to open a file and print the contents of the file to the terminal window. It works when I put the file right in the directory with the Solution but not if the file is out on my desktop and I use the full path. Here is the code:
#include <iostream> #include <fstream> #include <string> using namespace std; int OpenFile(){ fstream SampleFile;
I got a little question about getting the data path of my c program. I heard something like it's already given in the "int main(int argc, char **argv)". But with witch function can I get it?
For example: The program is called Pathfinder and the path is 'D:Path1Path2Pathfinder.exe'.
basically I need to list all of files and subfolders and files inside them etc till all paths has been inspected, read data from every single object and pack it all into a single file.
I did not want to use boost or minizip because it seems too much for something so easy so I just wrote it myself via dirent - everything works fine I just have problem with directories and files with non ANSI character in titles (I'm from Poland) like ąęoźż etc. I can open them without problem and read all data from them but when I pack their's filename to std::string - it gets corrupted and happend to be for example:
TEST~1 instead of TESTąę
Just a note that data inside files is being written without problems - all special characters are stored without problems.
The following code writes to a file on either local disk to a remote disk (commented out code) on Windows 7 platform.

The documentation does not specify what is a valid filename (path and filename). For example, will the "\server emp" path work on all operating systems to access a samba share? Does the constructor accept forward and backward slashes as folder separator on all operating systems?
im trying to write a file to a default document folder..something like...
FILE* file; file = fopen("%docdir% est.txt", "w"); fputs("Hello", file); fclose(file); "%docdir% est.txt" this isnt working for me, i have to write it as "C:userspublicdocument est.txt"
any method to write directly to default document folder so it will work in most Windows ? for example in windows 7 this is the default folder "C:users publicdocument est.txt" in windows XP its different
i have to detect the windows version first, to write the correct path
