Please help

I have this book programming for dummies and they gave a code I want to make sure the code is good and how do I see it on screen here is the code:
#include <iostream>
#include <stdio.h>
int main ()
{
cout << "It works!\n";
cout << "\nPress ENTER to contiune..." << endl;
getchar();
return 0;
}

Am I writing it right and what button do I push to see it and and is the code right??? I have no idea how to see what I wrote what do I press so new to this and I am scared.

..are ya using a compiler? can you click build?

did you receive any sort of documentation with your software?

btw the code itself looks solid, although I rarely mess with stdio.h.. if you remove "#include <stdio.h>" and "getchar();" you may find it still does what you want on execution.

I am using Dev C++ it came with the Programming for Dummies.

[cPlusN00b]

So.. open the dev program, go to new, start a new project, and create a new source file, put the code in there and click build, then run.

[CttLearner]

It says source file not complied after hitting run and I dont see a build button anywhere.

[cPlusN00b]

there's gotta be a build or compile button.. on mine it's right next to run. do you have an active workspace open?

[CttLearner]

I hit it and it is not letting me, they are saying line number 5
5 C:\Users\\Desktop\Seeifworks.cpp `cout' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)
6 C:\Users\\Desktop\Seeifworks.cpp `endl' undeclared (first use this function)

I have no idea what this means and do I need a new complier?

[cPlusN00b]

ah no
try inserting this statement right after your # command lines

using namespace std;

see what is says then

[cPlusN00b]

also if you get rid of "getchar();" (which i swear you may not need)
and replace these two lines:

cout << "It works!\n";
cout << "\nPress ENTER to contiune..." << endl;

with this one:

cout << "It works!\n\nPress ENTER to continue\n";

should be equivalent and then you won't need to include #include <stdio.h>

[CttLearner]

No good at all, I need a new baking sheet or a place to put this code down, a complier, do you know any that are free? Because it is because of that!

[cPlusN00b]

hmm. it really should work if all the include and header files are in the right place.. could ya post the code with "using namespace std;" included and exactly what the errors are when you try to compile. Here's what i'd try.

#include <iostream>
using namespace std;
int main()
{
cout << "It works!\n\nPress ENTER to continue\n";
return 0;
}

if it won't compile that code exactly then yeah you've got a problem with something else

[cPlusN00b]

and if there's a free compiler out there let me know lol I'd love to have it I am using educational version but can't legally distribute the executables developed with it

[CttLearner]

It works I wish they would have placed that before and Thank you very much!!!

[cPlusN00b]

glad to be helpful :3 yeah I totally had issues with my compiler at first.. I'll keep checkin this topic in case ya run into something else

[CttLearner]

Btw one last thing:

What does:

using namespace std;


mean????

[cPlusN00b]

my understanding is it tells the compiler to reference elements from the c++ std library.. Some people don't use it, instead prefixing certain statements with std:: (e.g: "std::cout << string;" instead of "using namespace std; cout << string;")
however, if you use cin, cout, and other std library entities more than once or twice in your program, it makes the code look kinda bleh to me, so just use:
"using namespace std;" and you won't have to worry about saying "std::" before everything
hope that made sense lol I don't know that much about it

[CttLearner]

You know more than me and I am more of a noob but all good we all have to start somewhere to be princes of the universe :-D
