I am using GCC on cygwin, but I want to browse for source file of string.cpp from the standard library . I just want to read the source file for knowledge of the function I am using, but the problem is I can't find it anywhere. I only find the header files but not the source files. I assume it is store somewhere else, or maybe in another...
If so, why? Why doesn't it use the copy constructor of the value type? I get the following error: /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/vector.tcc: In member functio n `ClassWithoutAss& ClassWithoutAss::operator=(const ClassWithoutAss&)': /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/vector.tcc:238: instantiate d f...

Hi everyone! I'm considering of data structure for storing a large array of strings in a memory. Strings will be inserted at the beginning of the programm and will not be added or deleted while programm is running. The crucial point is that search procedure should be as fast as it can be. Saving of memory is not important. I incline to s...
