    Question Am I on drugs ??

    as simple as this

    Code:
    #include<iostream>
    #include<string>
    
    using namespace std ;
    
    
    int main () 
    {
      string str;
      cout << "Please enter full name: ";
      getline (cin,str);
      cout << "Thank you, " << str << ".\n";
      return 0;
    }
    after entering the following : "Goerge Bush" I hit ENTER key...which should then display
    Code:
    Thank you, George Bush
    right ??Well it doesnt..what happens is following:

    after entering George Bush and hitting the "ENTER" key the cursor just jumps to the next line WHERE I AM ABLE TO ENTER ANOTHER FULL NAME.Upon hitting ENTER the second time the name "George Bush" is displayed (however not the second name ;not that i want to enter a second person)

    How is it that i get to input anything after hitting ENTER the first time...this never happened before

    I thought I knew what indigo0086 was getting at, but a quick check shows that getline() for std::string has a default argument of '\n' for its third parameter, so your code should work. I checked by compiling with MSVC8 and the MinGW port of g++ 3.4.5 and could not reproduce your problem.

    Exactly...thats why the title "Am I on Drugs"

    I never had the problem using Visual Studio 2005 or.NET

    However when using Visual Studio 6.0 the problem is rampant....

    I did some more googling on it and came across this...

    Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section. This problem was corrected in Microsoft Visual C++ .NET.

    this is the example code on the Microsoft site to illustrate the bug..

    Code:
    The following sample program demonstrates the bug:
    
    //test.cpp
    //Compiler options : /GX
    #include <string>
    #include <iostream>
    int main () {
    	std::string s,s2;
    	std::getline(std::cin,s);
    	std::getline(std::cin,s2);
    	std::cout << s <<'\t'<< s2 << std::endl;
    	return 0;
    }
    Actual Results:
    Hello<Enter Key>
    World<Enter Key>
    <Enter Key>
    Hello World

    Expected Results:
    Hello<Enter Key>
    World<Enter Key>
    Hello World

    what a pain...

    Sigh, so it was the old getline() bug. I suggest changing compiler. Why must you use MSVC6 when you have MSVC8?

    EDIT:
    NVM i will just hit ENTER twice
    If I remember correctly there is a fix that could be applied.

    I wasn't mocking you, roalme. It's just your program input and thread title screamed a pretty clever joke. I thought you put it there intentionally.

    The fix is in the page OP linked.

    But from what I have heard, you are going to have more "high" moments with that compiler.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
