I wrote a simple C++ program in VSCode. It is compiling without any issues, but the output is not visible on the VSCode integrated terminal. If I open a separate terminal externally using cmd, I can get the output. Can someone explain this behavior?
#include <iostream>
using namespace std;
int main() {
cout << "Weclcome";
return 0;
}

I'm a noob in C++ and I have VSCode running in Windows11 , with the typical extensions for C++ and MinGW. I am running a little code in this IDE:
#include <iostream>
using namespace std;
int main (){
int num;
cout << "Number: " ;
cin >> num;
return 0;
}
It is something basic for this test, but when I run it in the output option I cannot enter anything, neither letters nor numbers. Nothing comes up in the terminal option either. The code executes without errors and VSCODE does not give any information.
Instead, if I run the .exe file from outside the editor it works perfectly.
I don't know if it's my editor configuration error or some other problem, in Ubuntu or MacOS this has never happened to me.
I appreciate the help in advance.
All the best.
I installed Codeblocks on my Windows 10 computer. To check that everything works fine, I first compiled the simple C program
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("Hello world!\n");
return 0;
}
That works without problem but when I try the C++ equivalent:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!" << endl;
return(0);
}
Then the "command prompt" window opens but no output is shown. I can see in taskmanager that the program is running but as said without any visible output. I also tried running the program directly from the command line but with the same effect. Anyone any ideas?
I found the issue. There was still an older version of MinGW installed in a different folder. I deleted all instances of MinGW, and codeblocks as well. Adter I reinstalled codeblocks everything worked as it should.
This Guy solved similar problem with Codeblocks.
Remove the following Global compiler setting:
-Wl,-subsystem,windows
I'm trying to run this simple C++ code in Sublime Text on Terminal but it's not exactly working...
#include <iostream>
using namespace std;
int main() {
cout << "Hello world!" << endl;
return 0;
}
I'm getting this message instead:
"hello_world2.cpp:1:10: fatal error: 'iostream' file not found"
How can I fix this?
You most probably are missing development headers for your C++ standard library.
You didn't say anything about your environment, but if you were on Windows on Mac you would for sure get these together with your compiler, so let's assume Linux.
You need to install libstdc++-devel package or equivalent (libstdc++-4.8-dev etc.)
I am trying to write a simple project on Dev C++ , but it seems it is not working like it should on windows 8.
#include <cstdlib>
#include <iostream>
using namespace std;
int main()
{
cout<<"hello You~~"<< endl;
system("PAUSE");
return 0;
}
After compiling it, it shows an empty black screen. Am I doing something wrong?
There are known issues with running Dev-C++ 4.9.9.2 on Windows 8 (it's not that surprising, it's a program from 2005). Try a newer IDE - if you like Dev-C++, you can try Orwell Dev-C++.
somehow codeblocks decided not to run any new programs anymore. All I get is a black screen when running. Take for example the simple "Hello World" program. That will not even run. It compiles just fine without any error. All i see though when codeblocks opens is a black screen.
I tried looking online for help. It looked like this
Can't find file executable in your configured search path for gnc gcc compiler
would fix the problem. It didn't though.
This was my code:
#include <iostream>
using namespace std;
int main(){
cout<< "Hello World!" << endl;
return 0;
}
I don't know what happened and why. Sincerely hoping for an answer.
