As demonstrated, the most likely cause here is not hardware but the runtime: the program prints text but the console closes before the output can be read. Since reported Windows XP, that behavior is common when a program is started by double‑clicking its EXE. Changing the LCD will not affect this.

A reliable way to confirm output is to run the compiled program from a terminal/command prompt rather than relying on an IDE run button or Explorer. Typical Windows procedure: start a command prompt, change to the folder containing the executable, and invoke the executable. Example:

cd C:\path\to\build
program.exe

Running from a shell keeps any program messages and runtime errors visible.

If output still does not appear, check a few common causes: the project may have been built as a GUI application (no console attached); linker flags or build options may select the Windows GUI subsystem instead of a console; output may be buffered (no newline/flush before program exit); anti‑virus or permission rules may block the EXE; or the binary/path/architecture may be wrong. Turbo C++ and other DOS‑era compilers often behave unpredictably on modern Windows and are not a good choice for new systems or embedded work.

For moving into systems or microcontroller development, a modern, standards‑compliant toolchain and regular practice building simple console programs (run from the shell) are recommended before progressing to cross‑compilers and vendor SDKs. and provided useful pointers earlier in the thread about available IDEs and bundled compilers.

Place a cin.get(); just before your return 0; (at the end of main()).

Also by C++3.0 I think you mean: Turbo C++3.0? Don't use that crap anymore, it's been outdated for the last 10 years now. If you're going to start programming, please use code::blocks with the minGW compiler. It's up-to-date, compliant with C++ standards, free and easy to use. No excuse to use Turbo (not even if you're from India or the Philippines)

Pls advise as i dont have knowlege and iwant to start programming in C plz suggest me the exact and lattest and procedure for that.

Member Avatar for Nick Evan

Read my previous post and download code::blocks.

Then try this:

#include <iostream>

using namespace std;

int main() {
    cout << "hello world!";
    cin.get(); // keep the console window open
}

Then go here and follow the tutorials

Well cin.get() worked even i did n't dowlad code yet. Pls suggest or give me some info. as i have 7 years of SAP PM and Maximo experience no i want to go in system programming using c or C++ plz suggest me the best way to start and the lattest version. I 'd b really gratefull

Did you actually read any of my other posts? I gave you advice how to start, what more do you want?

Are you a student?
Lecturers tend to use TC, for some unknown strange reasons.
Here are IDEs I suggest

Visual Studio Express
Code::Blocks
Kdevelop
wxDevCpp
Codelite

They are not in order of aanything ;)
Just pick what you want, and will do a job

You should probably mention that most of those don't come with a compiler and are not useful for the OP. Which is why I recommended code::block with the mingw compiler (bundled). Easy to install/use and in 5 minutes from download to working installed version.

wxDevCpp | C::B | Codelite | MVC Express
All comes/have compilers version don't they?

wxDevCpp and Kdevelop don't as far as I know.

wxDevCpp and Kdevelop don't as far as I know.

wxDevCPP is just an extension of DevCPP which came with MingW. According to their website (on the FAQ page):

"We use the MingW compiler that comes with Dev-C++."

Which would seem to indicate that they are shipping with a rather old version of MingW as DevC++ hasn't been updated in years.

KDevelop seems to only have packages for Linux/Solaris in the downloads directory. They claim to have a Windows version, but I wasn't able to find one. (Maybe I just didn't look hard enough.)
