I'm a serious C programmer. Could any one tell me about C/C++ free online resources with lots of tough code for serious programmers. Plain text is preferable or in zip format.
absent any info other than that you're a serious 'C' programmer looking for tough code, i'd suggest you download the source trees for Linux (www.linux.org), Tcl/Tk (www.scriptics.com), or one of the Gnu tools, such as the gcc 'C' compiler (www.gnu.org).
