    reading a file in a different directory than where the program is located

    Hi,
    I am currently using fstream in C++ to read files. I have noticed that only file names are passed when opening a file. I was curious if there is a way to specify a different directory. The following does not work:
    Code:
    std::ifstream in ("C:\test\node1trans.sim");
    std::cout <<in.get();
    in.get() returns -1
    thanks for the help,
    Amish

    You forgot the \\ quoting of \ in your pathname.

    '\' is an escape character in C++. In fact, '\t' is a tab and '\n' is a newline character. Try this:
    Code:
    #include <iostream>
    using namespace std;
    
    int main()
    {
       
        cout<<"C:\test\node1trans.sim"<<endl;
        
        system("PAUSE");
        return 0;
    }
    To get the literal character '\' you have to escape it: '\\'.

    One further note is that forward slashes works as well ie. "C:/test/node1trans.sim" to avoid the double \\
