Main arguments in flex-bison

Question

Sorry for my English. I need to take the value of the parameters of the main function. I said in Bison:

int main (int argc, char ** argv)

I compile in Windows:

file.exe <input.txt

=>

argc = 1

and

argv = "file.exe"

Why? Thank you.

Answer 1

Try "file.exe input.txt", without the "<": argv[1] will be "input.txt".
