Thread: Does std::string supports wide characters?

The address of a[0] and a are not stored anywhere, they are a property of a[0] and a. The address of a[0] and the address of a are the same because a[0] is the first element in a. Think of a row of cars parked nose to tail. The start of the row of cars and the start of the first car in the row are at the same place. That place is not stored anywhere because there is no place for storing places on the street, there is only places for storing cars.

when I build my final executable using shared libs, I just replaced static with shared in makefile, also I have .a files availbale for static and .so files available for shared. I did small test, when I remove one library linking for static, I got many undef symbols, final exe file didn't built, the same test I did for shared, everytime execubale builts no matter whether I have all shared lib linking with -l option or not, looklike final...

Quote: You can not work out the size of allocated data from y alone, you need n too ...... size = sizeof(int) * n; That's the problem with using C/C++ arrays. If you want to avoid overflowing or out of bounds elements in the array, you must keep track of the size (i.e. the n value). If this sort of thing seems laborious and dangerous, try the STL vector. It deals with those issues.

You check for p[i][n].occupied==true condition when you print, but never assign .occupied the "true" value.

Hi, I want to implement the cstring class using wstring. but in assignement operator, I need to know how to add null while assigning some wchar_t type of data to the wstring. below is my code - class CString { public: wstring wStr; CString () {wStr = L"";} CString (wstring str) {wStr = str;} CString& operator =( const CString& stringSrc ); CString& operator =( wchar_t wcChar ); }; int main() { CString...

when I debug it was asking for an exe to debug with I chose the one it allowed me to without typing but that doesn't work. How do I change it now ? second unless I have a code back to the header how am I going to test the code ? so do I connect it to the exe that I've now made then change the code to point towards the header and act on the codes ?

I hesitate to take this further after the comprehensive treatment above as am no expert however here is a coded example from my book "Programming with C++" by John R Hubbard pp 331 Expand | Select | Wrap | Line Numbers #include<iostream> #include<vector> using namespace std;   typedef vector<double>Vec;...

Car parking example was awesome.Really a gr8 explanation A big thanx to you Banfa.You are gr8.
