problem with reading a txt file into vestors of vectors

Hi, i have the problem mentioned in the header: my file looks as this:

Iso: pfmzv600ta70lp703
T050S 1
D05030 2

Iso: pfmzv600ta70000
T050S 1
D05030 1
R0500200S 9
R0501000S 1

and so on. All terms shall be stored into different containers:Iso.. into a vector, T050S and so on into a vector< vector<string> > and the numbers like 9 into vector< vector<int> >.

my code is this:

1

i do not get any error messages from the compiler (dev-c++), but a windows-window pops up and says "there is a problem" and the program doesnt work. could anyone help me?

best, sajakob

Wrong forum, and please don't double post.

okay, thanks. went to the windows-based forum, although i think it is a code problem.
