Question

I’m trying to run a .exe from c++ using system. The argument, a text file, is asked for after calling the .exe. I need a way to provide this argument.

To clarify in bash I can do this:

cd /programlocation
wine program.exe

This then outputs,

Enter input file name :

If i now type

inputfile.txt

It works, but I cannot figure a way to combine this last step so I can run it using system from c++.

ie. This doesn’t work:

std::string location = "cd /location/"
std::string program = "wine program.exe"
std::string input = "inputfile.txt";
std::string command = location+"&&"+program+"&&"+input;
const char *cmd = command.c_str();
system(cmd);

This just asks for input file in the console.

If you can access it the program I’m trying to run is the a8711v30 esdu aircraft engine noise prediction file.

Answer 1

if program.exe is reading from stdin and not from the terminal, then you might be able to call system with the string:

cd /programlocation && echo inputfile.txt | wine program.exe
