C++ File Generator

Mar 29th, 2007

Hey all, I'm new to this forum, first post.. so please excuse me (also excuse the perhaps not so eloquent style, it is still in preliminary!) =). I'm writing a short piece of code in compliance with a webserver I've been programming with a group. This code is to auto generate an assorted sizes of files (which will later be used to test latency timings and average GET request timings) starting from size Class 0 which are files less
than 1KB, class 1 files are less than 10K, class 2 files are less than 100K and class 3 files
are less than 1MB. It should auto-populates the specified directory with the four
classes of files. There will be 9 files per class. Files in class 0 are in increments of
0.1KB (starting at 102 bytes) while class 1, class 2 and class 3 are in increments of 1KB. Syntax to use the code is HTMLGenerator -d <directory>. Output files should have the form of class<classsize#>_<increment>.

My greatest problem is that our school's compiler is old and does not contain <sstream> hence making my INT to String conversion difficult. Currently the code seg faults, likely due to improper usage of the *buffer. Any questions regarding the code I will promptly reply as I'm still working away. Any suggestions on how I can get this done? Thank you all greatly for your time and help ! =)
