Can't run newly compiled helloworld.o (New User) [message #1613]

I'm a computer science student and we just switched from java to c++.

I just started using Ultimate++ and 'theide' but when I compile the simple "HelloWorld" code below, I get an output file helloworld.o, and I can't figure out how to run it.

#include <iostream>
using namespace std;

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

I'm running Kubuntu Linux Breezy 5.10

Thank you for any help.

Mike

*.o is not an executable. Use Ctrl-F5 combination to compile, link and run. From "build" menu open "Output directory" to see what you have got there.

I found a different output file "helloworld" from looking at the output directory as suggested but I can't run that either (no .exe because I'm not in windows)

I just got confused becuase I thought if you were in the same directory as the executable you could just type 'helloworld' and it would run, but I had to type './helloworld' for it to run

What happens if this:

#include <iostream>
#include <string>

using namespace std;

int main( )
{
 string s;
 cout << "Hello World!" << endl;
 cin >> s;
 return 0;
}

I've told you to use Ctrl-F5 combination... Smile

AFAIK, for console applications and Ctrl+F5, there is probably trouble in X11/Linux - if TheIDE is started from X11 GUI, it does not have any associated console and its console output as well as output of any of its child processes goes to nil.....

On Linux: you can switch Debug/Run options../Standard output to console to see the output after pressing F5 key (debug).
