CLion standard input while debugging

Question

What I\'m trying to do is basically:

./myProgram < myData.txt

While I\'m debugging with CLion IDE. I just can\'t find the option to do so.

Assuming your input file is myData.txt, you can reopen/reuse the stdin stream using freopen

freopen("myData.txt","r",stdin);

if you want to do the same with your output:

freopen("myOutput.txt","w",stdout);

this will work for std::cin, printf, etc...

You can find more information about this here: http://www.cplusplus.com/reference/cstdio/freopen/
