I have a string like this
const char *filename = "C:/Qt/progetti/worlds/fasr.world";
then I have a string like this
char *pathdir = "C:/Qt/progetti/worlds";
I would get this string: "worlds/fasr.world" how should I do ?
I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?
I have a program here that writes employee information into a text file called employee.txt. I don't have a problem writing into the text file.
I'm supposed to enter the employees ID and search for it. Then pull up all they're info.
This is what I have.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(){
ifstream inFile;
ofstream outFile;
[Code] ....
This is the text file
Viktor,Luc,552,123 Home,5000
Joe,Luc,553,123 House,7000
Create a simple data file like the example shown below containing the 4 dates below plus 10 or more additional dates. The file should include 1 date per line and each date should have the form MonthNumber-DayOfTheMonth-Last2DigitsOfTheYear with no extra spaces. All dates should be in this century. No error checking for invalid dates is necessary.
My Output displays like
February -19,1991
How do I get my program to ignore the dash between the dates?
#include <fstream>
#include <iostream>
#include <string>
#include <cmath>

So this may be against the rules, not sure, grey area probably? However I just bought the PC game Oil Rush, and was having a look at how the assets are packed. As with most games the textures, scripts, sounds and audio are all free to access.
However the game data such as maps, models and other, are packed into UNG files, i.e a custom encrypted file format, which probably is also compressed. So I googled for an unpacker/extracter and found one which also comes with the C source. You can download here. [URL] ....
So I am trying to figure out how these authors work out this file format, from the source we have,
Code:
static const u8 unigine_mask[] = "xffx7fx3fx1fx0fx07x03x01";
u32 unigine_key = 0xa13cdbde;
Looks like a password of sorts. You then have to work out the complete understanding of the file formats, headers, blocks etc.. How is this done...
I have a folder "pics" in g: drive. There I want to create some text.txt file. Thus, the final path is "g:pics ext.txt".
How can I do that?
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?
My output should be :
FILE *file;
std::string fullFileName;
file = fopen("input.txt", "rb");
if(file != NULL)
{
// getfullfilename(file, fullFileName);
// std::cout << fullFileName.c_str() << std::endl;
}
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 have a text file called (Test.txt) with the following text:
This is line one
This is line two
This is line three
How do I go about writing a program that will print a line of text (e.g. "This in line two" on the console screen?
All I can seem to do is display the entire text file.

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;

ifstream ipf("C:/Users/My/Desktop/C++/1.txt");

how to get source path of selected file.
for example :
selected image in E:/
E:ewfolderillustration.jpg
application - asp.net(C#)
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?
View 3 Replies View Relatedi want to create/open any file present in any location in my computer. How do I assign a path in C++ syntax?
View 1 Replies View RelatedI'm writing a small function that gets as parameter a file's path and a folder's path, and copies the given file to that folder.
Code:
int copy_file(const char* source, const char* folder) {
char copy[PATH_MAX];
strcpy(copy, folder);
strcat(copy, "/");
strcat(copy, source);
[Code] ....
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...
I'm working on windows and I'd like to know how to compile the C file to a different path.
What I mean is : the basic compile command is :gcc Hello.c -o Hello_E
I'd like to create the "hello_E" in a different path.Something like this:
gcc Hello.c -o C:Program FilesPellesCC_programsExe_filesHello_E
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 /.
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.
./movie_stats < ./input/test1.in ./my-output/test1.out
What I'm thinking is to open/create the file test1.out in the my-output folder and open it at runtime?
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 :
private void NewJournal_Click(object sender, EventArgs e)
{
string filePath = @"E:New ABCabc.vnalog"
if (!File.Exists(filePath))
{
return;
}
string SelectedFile = @"/select, " + filePath;
System.Diagnostics.Process.Start(@"E:New ABCabc.vnalog", SelectedFile);
}
Now this code open the .vnalog file in the application. And this works great..!!! How can I now change the path within the application?

We have an assignment to produce code to gather a string of input from the user in which they are entering a date. We then have to extract parts of that string to make substrings, and display different formats for the date(I will add my code in here so you can see what I have done). It took me a long while plucking away at this to understand this part. You will see that at the end of my code I have opened a file months.txt. We were provided with a file which states months corresponding to dates. I.e. 01January 02February 03March 04April, and so on until December. Exactly how I have typed it is how it is in the file.
I understand how to open and extract what is in the file as a string. I have extracted this as a string called myMonth (as you can see in the code as well) NOW,
I am supposed to have the program search for the month in the file, matching that to the month the user has input earlier, and then use the number infront of that month. I understand the basics of using find(), and making substrings. But how on earth do you get the computer to correlate what the user has input for a month, to finding that in the file, and then using the correct number.
Here is the code I have done so far:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
string myDate; // Date input from user;
string myMonth; // Input from months.txt

Extracting integers from a string is trivial, but I am unable to find a function or code that will extract decimal numbers from a string.
I have a string that looks something like this:
" Asdf 1 1.3825 4.0000 12.0000 1.9133 0.1853 0.9000 1.1359 4.0000 "
Any tips on extracting the numbers (in decimal form) and storing them in a vector?
