如何编写打开exe文件（spectrawin）并将数据保存到特定名称和文件夹的程序？

Question

I'm using c++. How do i write a program that opens an exe file(spectrawin) and saves the data into a specific name and folder?

Cheers

Answer 1

This will make a directory called Output, and pipe the output from your executable into a file called output.txt, inside that Output directory.

mkdir ("Output");
chdir ("Output");
system ("spectrawin > output.txt");

Please note that I do not know what spectrawin does. The above code works with an exe that outputs to the console.

Incidentally, if you need to know where your working directory currently is, use something like:

char workingDir [_MAX_PATH];
_getcwd( workingDir, _MAX_PATH );
