Script to test C++ programs

Question

I want to write a script (Windows 10) which will be testing my program. I have not found any suitable answer so I decided to open my own question.

I have files with input and output for my program eq.:

stud1.txt and stud1_out.txt alternatively.

My C++ program reads input from console (std::cin).

I know how to compare files (FC command) and how to run program from command line, but I have no idea how to pass on input data to a program which reads data using std::cin and then write it into the file to be able use FC command.

Thanks for any help :)

Use < to pass file contents to the STDIN of a console program, e.g.:

console_prog.exe <input.txt

@pjdev: use `>`. Sample: `console_prog.exe >output.txt` – Dmitry Egorov Apr 18 '17 at 13:33
You also can combine both redirectors: `console_prog.exe output.txt`. And even do more useful tricks. Please see the article I referenced. – Dmitry Egorov Apr 18 '17 at 13:38
