help with beginning code

[deathscith]

code:

#include <iostream.h> main() {     cout << "Hello World!";     return 0; }

should probably of stated more in the subject name, but it isnt really help needed for the hello world code, i use the compiler MinGW, and everytime i compile this program, and i've done this with devC++, the problem is that when i compile it, it creates an exe oviously, and when i open the exe it opens it in cmd promt, but it closes instantly... how do i get it to stay open?

[deathscith]

alright, well could anyone help me with my quick solution? make it so it awaits a command to exit?
kinda like for turing (only language i know much of)

code:

var base : string := "" var exitstate :string loop put "hello world" get exitstate if exitstate = base then put "" else exit end loop

This is a common issue.

Open it in the command line, cmd.exe on Windows. Simple C/C++ programs aren't meant to be run in they way you are attempting to run them.

Also, don't post "bump" 2 minutes after you post your help topic.

*edit* No refresh, wtd wins.

i'll remember that gandalf, and as for my problem, the link you said gave me this as my desired outcome

Quote:

This is the poorer choice, and only masks the problem. Add code to your program that prompts the user for input. The program will not complete until the user actually does input something, meaning that in the meantime the console window remains open.

but how do i do that?

[wtd]

Good question. You have something new to learn.

[deathscith]

where would i go about as to learning this? i've looked through a few of the beginners tuts and they never give this info...

I just want to point out that...

yea, but its what i want it to do.

[Ktomislav]

code:

#include <iostream.h> using namespace std; main(void) {     int a;     cout << "Hello World!";     cin >>a;     return 0; }

That's the way i do.

Also, it should be:

code:

#include <iostream>

not

code:

#include <iostream.h>

[wtd]

Congrats on just feeding deathscith an easy answer.

Yes. I copied that code from the post above and i didn't check it if it is correct.

cin >> a
will wait until you hit the <ret> key.
If instead you use
int c = getch();
They any single key at all will work to end it.

cout and cin are not in the standard name space, problem number one.

waiting for needless input at the end of your program is such a bad practice that anyone who recommends it should be shot. Or failing that banned from programming. Ever.

Instead you should run your program from a command line, like command line programs are mean't to be run. Compilers are command like programs too! So if you compile your code using a compiler on the command line you already have a ready to use window to run your just created executable in! Plus using the command line will get you much more familiar with the compiler and many other different parts of your system which are really quite handy.


Rigby5, getch is a windows only function. Unless you include some additional libraries which are well beyond a hello world program, getch will not exist.
