Why don't you just put the text file in your hard drive like D:\ or something? Then the program will work on every user on the computer.

myfile.open ("/home/ws14/Desktop/test.txt");

myfile.open ("/home/ws14/Desktop/test.txt");

for example: /home/ws14 is my user. but if I transfer the c++ file to another user it cant open the path /home/ws14. because it is not the same user. how do I make the path general? with a folder. that you dont need to change the code for the user and another user. thanks!

on a u*x system, / is your root. /home/ws14 is a private home directory, so you probably need to place the text file into some public directory instead. if you don't care on whose desktop the file is, you can try accessing ~/Desktop/text.txt, but it will be up to the other users to ensure they have such file on their respective desktop.

Because it is Linux, so D:\ won't exist



You could get the username by using popen in combination with whoami :

#include<iostream>
#include <cstdio>
using namespace std;
 
int main()
{
    char text[255];
    FILE *name;
    name = popen("whoami", "r");
    fgets(text, sizeof(text), name);
    pclose(name);
    string path = "/home/" + string(text);
    cout << path <<  "\n";
    return 0;
}

#include<iostream> #include <cstdio> using namespace std; int main() { char text[255]; FILE *name; name = popen("whoami", "r"); fgets(text, sizeof(text), name); pclose(name); string path = "/home/" + string(text); cout << path << "\n"; return 0; }

I didn't test it, but I think it should work. There's probably a better/cleaner way to do it. Perhaps use "~" in the filename?

[edit] too late...
