is this an acceptable way to pull things from a file?
or is there some better more effective way?

uhm the ignores are so i can bypass all the things i dont need...and just pull the 2 names from both number 2 and number 5...try out the code...put all of the stuff at the bottom in a txt file...and try it -_-

hey thx...yea that is exactly what i had figured...because most indefinately the project that im attempting...will have rather large files...definately larger then 10000...

>> ifstream File("map.tbw",ios::in);

If you specify an ifstream object, it's all ready for reading from a file no need for the ios::in

Code:

ifstream File("map.tbw");

-Futura

If you specify an ifstream object, it's all ready for reading from a file no need for the ios::in

yea but if you check my code its made for writing and reading...
so i dont have to define 2 different fstreams...just one -_-

Code:

fstream File("map.tbw",ios::in|ios::out);

oh sorry...my bad ;P
