copied!<p>My programs have been running properly for over a year. Today I copied the files onto a different system and compiled every program.</p> <p>When I compile and run from Dev-c++ it writes data onto a text file like its supposed to, but when I click on the executable it creates, it does not write data onto the file. Everything else like input/output seems to work.</p> <p>What procedure have I missed?</p> <p>Ok i've given the program Full permision but it still does not write.</p> <p>I'm quite puzzled, atleast if it didn't run when i compile it in the C++ environment i can keep checking my code, but only the .exe does not work, any other suggestions ?</p> <pre><code> #include <iostream> #include <fstream> using namespace std; int main() { ofstream bss2; bss2.open("expat.txt",ios::app); bss2 << 2 ; bss2.close(); } </code></pre> <p>This is the sample code i tested out.</p> <p>How do i find the Current working directory ?</p> <p>Ok i changed a line to </p> <pre><code>bss2.open("c:\\expat2.txt",ios::app); </code></pre> <p>and now it works properly in the exe file.</p> <p>but there's over 50 files and i prefer i didn't have to spell out the new path to each one, what workaround is there to set the directory to the one previously used ?</p> <p>update 4 :</p> <pre><code> #define _POSIX_SOURCE #include <unistd.h> #undef _POSIX_SOURCE #include <stdio.h> main() { char cwd[256]; int y; if (chdir("/tmp") != 0) perror("chdir() error()"); else { if (getcwd(cwd, sizeof(cwd)) == NULL) perror("getcwd() error"); else printf("current working directory is: %s\n", cwd); } scanf(y); } </code></pre> <p>Ok i used the getcwd() and this is the message it gives me</p> <p>chdir() error(): No such file or directory</p> <p>How do i set the directory now.</p>
