How To Sort An Array

The same sort function used to sort STL vector can be used for sorting arrays also. Surprised? Sometimes life is easier than we expect. 

#include <iostream>
#include <algorithm>
using namespace std;

int main()
{  
   int MyArray[] = {10, 9, 8, 7, 6};
   sort(MyArray, MyArray + 5);
   for (int i = 0; i < 5; ++i)
   {
      cout << MyArray[i] <<'\n';
   }
   return 0;
}

How To Convert CString To TCHAR*

See the following code segment.

CString myCString = _T("Hello"); 
const TCHAR* myCharString = LPCTSTR(myCString);

Some Background Info

1. TCHAR will be evaluated to char if _UNICODE is not defined. Otherwise it will be evaluated to wchar.
2. LPCTSTR is also a data type which is nothing but const char* or const wchar*, depending on whether _UNICODE defined or not.
3. CString has a constructor which accepts TCHAR*.
4. The macro _T will make the supplied string neutral. That is, if _UNICODE is defined, the string will be in 16 bit unicode format, otherwise in 8 bit ANSI format.
