std::cout outputting in wrong order

I have a vector of structures which contain filenames of type std::string. When I use std::cout to output these strings like so:

Code:

for (iter=files1.begin(); iter != files1.end(); iter++)
    std::cout << iter->fileName << "\n";
std::cout << std::endl;
for (iter=files2.begin(); iter != files2.end(); iter++)
    std::cout << iter->fileName << "\n";

I get the output:

Code:

file1.txt
file2.txt
file3.txt
file4.txt
file5.txt
file6.txt
file7.txt
file8.txt

When I should get:

Code:

file1.txt
file2.txt
file3.txt
file4.txt

file5.txt
file6.txt
file7.txt
file8.txt

There's not enough code there - are you sure that the files2 container actually has anything in it? The output suggests that the container is empty.

You were right! I was accidently adding the structures on the end of files1 instead of file2. Opps! I'll remember to read my code more throughly before posting next time
