File input/output help! C++ using xcode

[boyongo]

Hi everyone Im using xcode in c++ language and I am having trouble finding the place to save my txt file so the program would recognize it.

This is the code i have.


#include <iostream>
#include <fstream>
using namespace std;
int main (int argc, char * const argv[]) {
int x;
ifstream in;
in.open("Input.txt");
if(!in)
{
cout<<"\nProgram cannot find the input"<<endl;
return 1;
}
in>>x;
while (in) {
cout<<"Number"<<x<<endl;
in>>x;
}
in.close();
return 0;
}
The program displays the cout inside the if so its clearly not finding the txt file.
If anyone can help me please do.

Thanks

You should store the directory to the file in a string or char array and access it from there.

const char file[] = "/Users/Home/Desktop/file.txt";
ifstream in(file);
if (! in)
     exit(1);
else
     do stuff

Hope that helps.

File input/output problem.

Hey dissolve i tried it but i dont not worked. If it does not bother you perhaps you can be more clearly with the code. Try modifying the code a placed in the thread so i can have a better idea. Sorry for bothering so much.

Problem solve!

I solved the problem.

This is the code i had.

#include <iostream>
#include <fstream>
using namespace std;
int main (int argc, char * const argv[]) {
int x;
ifstream in;
in.open("Input.txt");
if(!in)
{
cout<<"\nProgram cannot find the input"<<endl;
return 1;
}
in>>x;
while (in) {
cout<<"Number"<<x<<endl;
in>>x;
}
in.close();
return 0;
}

The in.open("Input.txt"); part were you put the direction were your txt file is located is wrong the way it should be is:

in.open("/Users/the name of your computer/name of the file.txt")

if you have it on your desktop it should be like this:

("/Users/the name of your computer/Desktop/name of the file.txt")

If you have it on a folder in your desktop. After desktop put the name of the folder between / /:

("/Users/the name of your computer/Desktop/name of the folder/name of the file.txt").
And so on.

Hope this help.
If not ask in the thread and i will try to help you.

I'm sorry, I should have been more clear. Yes, "Home" is referring to your Home directory. Glad you got it figured out

The place you want to save is in the current user's directory "~/" + subfolder, if any.
