Simple Script Language Questions

[YayPython]

I actually got a small script language working, all by myself.

However, there are a few things I would like to figure out:
1. To open a file, I get input (for the filename) and save it to a char variable. Then, I use an ifstream to open the variable. That works great. However, I want to make it so when you double click on a .hs file, it will automatically pass the file location to the char variable. When I double click on my .hs file, it opens the program and asks me where the file is. I just want it to bypass that step so you don't have to type that in if you opened the file, but I do want ti to do that if you just run the program. Is there a way to do this?

2. I want to make it so the interpreter completly ignores a line in the file if it beins with // (Comments.) I have it set up so it reads each word in the file, sends it to a huge array, and then a for loop reads the lines and checks to see if it's a command. Ex:
Psuedo code:

Code: Select all

lines[100000]
open file.txt
read file.txt
send lines to lines[]
for(i=0;i<20;i++){
if(lines[k] == "$dos()"){
  dos()
}
etc...
}


How can I make it ignore everythong on the line after the //? I'm not asking for code, maybe a few hints and a links or two.

first of all, if you are using C++, don't use chars unless it is appropriate for the situation.
second of all, if you are using C++, don't use arrays unless absolutely necessary.
third, in windows you should be able to associate a 'hs' file with your program by right clicking a .hs file, hit properties, and click the button to associate it with a program. then find the program, and then .hs files should attempt to open with it.
fourth. post some code so we can get an idea of what your issues are, and be more verbose.
