fatal error: iostream: No such file or directory

[raysonkong]

My first program won't run. it says" fatal error: iostream: No such file or directory".
Can someone help?
Thanks in advance.

 #include <iostream>

using namespace std;

int main ()

{
      cout << "Hey, you I'm Alive! Oh, and Hello World!\n";
cin.get();

}

I don't see any thing wrong with this program you might want

int main( int argc, char* argv[] )

or try and tab over cin.get();

otherwise try :

int y;
cin >> y;
return 0;

Use the C++ compiler. For instance, g++ and not gcc.

From the command line, something like:

> g++ -std=c++11 -Wall -Wextra -pedantic-errors -o my_program.exe my_program.cc

works fine for me. What compiler are you using?

I am wondering why the cin.get();is there at all. why is it there, when I ran it it my virus protection came up and said it was a threat, but i took the cin statement out and it ran fine no problem at all, so, why, why is it there at all?

To make the program wait till the user types in something. Useful, if the program is run in a new terminal window, and without it the window would close instantly.

Your virus protection is talking through its hat.

Well wouldn't be easier to use a variable? Such as

#include <iostream>

using namespace std;

int main()
{
      cout << "Hey, you I'm Alive! Oh, and Hello World!\n";
      int x
      cin >> x;
}

or even

#include <iostream>

using namespace std;

int main()
{
      cout << "Hey, you I'm Alive! Oh, and Hello World!\n";
      system("PAUSE");
}

either of these would work better in my opinion for a beginner programmer

> Well wouldn't be easier to use a variable? Such as

Formatted input (>> into a variable) is required if there could be white space left in the buffer after an earlier formatted input.


> system("PAUSE");

In general, prefer not using std::system() when you have a reasonable alternative. http://www.cplusplus.com/forum/beginner/93213/

I agree, but I'm talking about BEGINNER programming, and a beginner wouldn't need to worry about malicious software in their applications would they? or is there a virus that attacks new .exe's as you create them? or is it sooooo slow that it would be bad for a beginner to learn? I learned it as a beginner and I don't use it anymore so I don't see why not learn it and when it is unnecessary no longer use it, it is not hard to un-learn

[raysonkong]

Thank you so much everyone. I am using Code blocks 12.11


Still won't compile.....

[raysonkong]

hey guys, i turns out I missed some basic steps when I start the code block application, now the program runs fine. Thanks again

[twiggystardust]

if I may ask...what was the problem?

Programming is a lot easier if one cultivates good habits. And cultivating good habits early is a lot easier than breaking out of bad habits later. Learning x, unlearning x later, and then learning y is a lot harder than learning y in the first place.
