Thread: freopen and strings

hi guys, new here...seems like a very helpful site...

so on with the question.

I was asked to write a program using the argc and argv cmd line arguments and also freopen.

here is what is has to do

3 txt files are the cmd line arguments

using the str commands, I have to somehow search through one txt file which is a written paragraph looking for a <tag1> then a <tag2> and then replace them with what is in the secon text file whick looks like this:
<tag1> example1
<tag2> example2

of course I cannot show the tags, only the example when replace which is written to the 3rd txt file.

I get the cmd line and freopen stuff no prob, I am just very very weak with strings.

please help

freopen() eh? Personally I'd use fopen()... but its your choice.

As for the strings, you're about to learn a lot about char array manipulation. Try looking up strstr() to start with.

Also, you'll need a 2-d array to hold the words from the tag list file (or a hashtable, list or tree).
