retaining the output of a program onscreen [was: what the ****]

[robacid]

How come when i compile and run this this script or any script for that manner

// my first program in C++

#include <iostream.h>

int main ()
{
cout << "Hello World!";
return 0;
}

I can see the dos window appear and flash away really fast before i can read nething plz help me. -Rob

I guess you run via VC. If you want to see the output, you have to run via command line. :)

srry i dont understand what you mean im a complete newb o.0 I am pretty intellegint lol spelled that wrong ) so can you try and explain it a little bit to me thank you very much :)

//try this:


#include <iostream> //modern c++ fix
#include <system>
using namespace std;

int main ()
{
cout << "Hello World!";
system("pause"); //call the old dos pause routine -- adds a 'press a key' thing
return 0;
}

you can also open a command window (cmd.exe -- start, run, cmd)
and change to the location of the exe and run it from there.

If you run from VC it adds the system pause for you -- its a nice thing mircrosoft did for you. Other compilers will not do this.

\Documents and Settings\Static_Life\My Documents\C++ tutorial files\Hello World.cpp C:\Documents and Settings\Static_Life\My Documents\C++ tutorial files\C system: No such file or directory.

when i make a compile and run a script or a program i have made the dos window pops up and closes before i can even read it =P plz help

THere should be a version of the standard system.h include file in there -- thats the easy way. you can also read in a string, or again, simply navigate and run the program.

start - run - cmd
in the command box:
cd\
cd somefolder\otherfolder.... //go to where the program is
myprogram.exe //you dont have to type .exe

maybe your compiler is older
go back to iostream.h and system.h then -- those should both exist.
system lets you do operating system commands -- like dos's dir command.
Pause is a dos command (its for batch files).
