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;
}
How to get a full path of a directory only using a text file name? (Btw i am using visual studio not windows)...

Code:
scanf("%100[^

But that's not working for me. so i came up with my own function and its not giving me the results i want. here is the function including the call from main:
Code:
/* * * * * * * * * * * * * *
* FROM MAIN *
* * * * * * * * * * * * * */
printf("

printf("Enter part name: ");

Where is the eight coming from? i thought fpurge clear the buffer. Also, I'm trying to add spaces in between words... i thought maybe putting within the while loop but outside of the if statement string[length +1] = '' would work, but it doesn't. so i put it outside of the loop but that i knew that wouldnt work either.
Problem #2 is reading from a file.. so far i have the following code which reads everything perfectly except the .txt file has a new line character at the end and i think its reading it:
Code:
/* * * * * * * * * * * * * * * * *
* READS FROM FILE *
* * * * * * * * * * * * * * * * */
if(read_in != NULL)
{
while ((fgets(read_string, MAX_PARTS ,read_in) != NULL) && (array_position < MAX_PARTS))

The program needs to be able to read the middle names within the text file named Info2.txt
Simply adding the Mname or any related value where the other to name values doesn't do anything and only the 1st line appears on the output.

That is the correct way it appears in the text file. Also I know it's commented out, but that just to keep the program from crashing.

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 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 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);
}

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...}
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?

void clrscr();
}

if i enter my full name i will be able to go on to the next statement/command but when i put on some name (which is not mine) i will automatically get an error and exit the program.If i type "Qwerty You Tube" EXACTLY and not just the first string before the whitespace i will be able to proceed but when i enter "Qwerty Tube You" or "Qazse Qop Queen" i will get an error and the program will exit.
I have a code to check the last time modification of a file using "gmtime". Is it possible to remove the seconds in the result?
Here is my code:
struct tm* clock;// create a time structure
struct stat attrib;// create a file attribute structure
stat("test.txt", &attrib);// get the attributes of afile.txt
clock = gmtime(&(attrib.st_mtime));// Get the last modified time and put it into the time structure
Why is this code not marking that the queue is full.. I'm just including my Add function that verifies if they want to add another number to the queue. The isFull function works fine, have used it on other programs.
template <class T> //Template currSize function
int Queue<T> :: currSize ()
{
return (rear - front + arraylength) % arraylength; //
[Code].....
The output goes all the way down to 1 spot left, lets the user enter the last element. Then it asks if they want to add another.. At this point, when they hit Y, it lets them add it and it says there are 5 spots left!

It seems like my program doesnt want to take in a sentence, only the first word i type in
I'm trying to design a C program that ask the users to type their full name (seperate by a space), and store this name in a two dimensional array. I just want to test if I did it correctly, so i just entered one name and give it a try.
char name[50][2];
printf("enter the neame");
scanf("%s%s",&name[0][0],&name[0][1]);
printf("%s",name);
return 0;
but the program will not print the expected result.
It's really simple to say to a pointer to point to a sigle character or a single number.
Code: int *ptr;
int a = 5;
cout << *ptr << endl;
But I want for example a pointer to change a whole text line. My idea is that the user enters which language he speaks.
Code: cout << "English" << endl;
cout << "Swedish" << endl;
But I don't know how to this. I could have done this without pointers with if statments but I want to do it with pointers because it were a exercise to do.
So, I'm making a program in C++ that emulates a full screen console... I used SetCurrentConsoleFontEx to set the font to 12x16 but it sucks...
Anyway, I read here: [URL] .... that also the console font can be changed, but I can't make it work! How can i set the font to Lucida Console? This is the function I use to change font size:
void setFontSize(int x, int y) {
PCONSOLE_FONT_INFOEX lpConsoleCurrentFontEx = new CONSOLE_FONT_INFOEX();
lpConsoleCurrentFontEx->cbSize = sizeof(CONSOLE_FONT_INFOEX);
GetCurrentConsoleFontEx(GetStdHandle(STD_OUTPUT_HANDLE), NULL, lpConsoleCurrentFontEx);
lpConsoleCurrentFontEx->dwFontSize.X = x;
lpConsoleCurrentFontEx->dwFontSize.Y = y;
SetCurrentConsoleFontEx(GetStdHandle(STD_OUTPUT_HANDLE), NULL, lpConsoleCurrentFontEx);
}
