So I'm making a file that takes in the input file name as an argument argv[1].

int main(int argc, char *argv[]){

std::ifstream inputStream;

inputStream.open(argv[1], std::ios::in);

}

My issue is that I need to use the fileName/Stream, argv[1], for a function in another function. How do I pass it twice?

ex:

main.cpp -> gets argv[1] -> initializes func1.cpp

func1.cpp takes argv[1] -> initializes func2.cpp

So initially I have in int main

Func1 func1(argv[1])

Now func1 has argv[1], but within func1, how do I pass it again into func2?

Essentially I need the second function "func2" to run through the stream but send up info into the first function "func1" which will then interpret the data and print into main.
