I have to ask the user to enter a value which he could leave empty if he wishes to.
If I use cin, it is required that he enter something at least
getch() - when he uses backspace, the character is not deleted
getline - requires him to press enter twice
scanf - requires him to enter something at least
gets - sometimes the program skips the code.
could somebody help me out with this,
Shilpi
This is a bug with the library. Unfortunately, I'm not sure how to fix it. Maybe somebody else can enlighten us...Quote:

If you're using Visual Studio 6.0 or less, check out this page,
which gives many bug fixes to "tide you over" until Visual
Studio .NET: http://www.dinkumware.com/vc_fixes.html
In particular:
Quote:
The header <istream> contains a definition for member function basic_istream::getline. It has a lookahead problem -- typing a delimiter to end the input doesn't return control until you type yet another character. Change the code as indicated by the comment:
Code:else if (_C == _Di)
{++_Chcount;
rdbuf()->snextc(); // replace snextc with sbumpc
break; }

Note that V6.0 replaces snextc with stossc. It is an adequate fix, but you can also apply the above patch safely.
Why is it that sometimes, my program does not ask the user for input even if I have used gets();
