I installed VSC and wrote this program
#include <stdio.h>
int main( void )
{
printf("Hello world!");
}
Then I installed a C/C++ debugger and I saved the file on the desktop as "hello.c" and magically the syntax became higlighted.
Now I would like to run the program, but can't find a way.
There's no "run" or "build" option anywhere, and if I start the debugging and choose the debugger then I got a new tab named "settings.json" with a couple of brackets waiting for me to write something.
Also in the left I can read that I "have not yet opened a folder". What does it even mean?
And the line #include <stdio.h> is underlined in red, like there's something wrong going on, maybe I have to download the library?
I would do anything to see the output of the program, please help me.
have you added c/c++ and code runner extensions?

I haven't found any extension, or tutorial to make and execute a C console application in the VSCode Terminal.
A simple program like
int main()
{
printf("Hello World!");
return 0;
}
And have the output in the VSCode Terminal.
Does someone know how to realize this? And/or are there solutions?
Thanks in advance

There actually is an extension for c/c++ on VSCode:
When you click the arrow in the top right (to run the file) you will be asked which compiler you want to use. In our case we can use the gcc compiler:
Then you can paste your code into a .c file and run it with the compiler. It should automatically also execute the binary and print your output into the debug-console:
#include <stdio.h>
int main() {
printf("Hello World!");
return 0;
}
Hello World!
You even have a debugger, if you set certain breakpoints!
Extra:
Make sure that you have the correct OS set in the bottom right (in the status bar), so your c code compiles for your machine specifically.
So, after running this code in Visual Code:
#include <stdio.h>
int main(){
printf("Hello!");
return 0;
}
I get this in my console:

What's up with all that added text?
Because you're running your program under Visual Studio Code's debugger, and for some reason it prints out a bit of job control trash on the console.
Maybe add a newline at the end of your print, to make your output clearer:
printf("Hello!\n");
Alternatively, don't run under the debugger (look for a "Run without debug" option).
I'm on the first CS50 lecture and I'm entering the code into VS Code exactly how I thought it was supposed to be, but for some reason I keep getting the errors at the bottom. It keeps telling me when I try to run make helloweb that the make function doesn't exist 😪
Here's the code.
#include <cs50.h>
#include <stdio.h>
int main(void)
{
string answer = get_string("What's your name? ");
printf("Hello, answer\n");
}
I fixed this issue by running cs50 through Codespaces.
Go to https://code.cs50.io/ and log in with GitHub. After that, you should be able to run Codespaces through VS Code natively by installing the codespaces extension for VS Code. Finally, launch https://code.cs50.io/ through a browser and click "Open in VS Code Desktop".
I'm beginner for C language and for Eclipse IDE. I've downloaded and installed Eclipse ide for c/c++ developers i.e. Mars 2.0. I've created a new project and selected the appropriate compiler and typed the following code:
#include <stdio.h>
int main()
{
printf("Hello, World! \n");
return 0;
}
After, when click build project it creates .exe file for me and when I click on Debug it successfully Debugs but shutdowns automatically within a fraction of a second.
From what you've told us, that would be correct. If you want to step through the code, you have to set a breakpoint. You should be able to double-click in the margin on the "printf" line to set a breakpoint there.
I've started programming in C so weeks ago, and I choose Eclipse Kepler as my IDE for C, since I had already used it for programming in some other languages and really liked.
However, after I had installed Cygwin and the C programming tools in Eclipse, I tried to run the old "Hello World" and it didn't work, It didn't appeared anything in the Console, only the message "Terminated".
#include <stdio.h>
int main(){
printf("Hello World!");
return 0;
}
Anyone has any idea what the problem could be?
Thanks to all of you. I tried everything you said but I wasn't able to get my problem solved. I gave up! Right now, i'm using as workspace in eclipse the Cygwin home. I write the program in the Eclipse and run it in the Cygwin command line.
Again, thanks to all for trying to help, it won't be forgotten. You're a really awesome crowd!
Maybe the program was too fast for you to see it?
The window with the program output appeared and disappeared in the blink of an eye.
You could try to prevent that from happening by changing your program to do its stuff AND wait for ENTER before it terminates.
#include <stdio.h>
int main(){
printf("Hello World!");
getchar(); /* simple wait for ENTER, error prone in more complicated programs */
return 0;
}
Note: your original program "prints a string"; this version "prints a string and waits for ENTER". It's a program with different requirements. If you want to keep to your initial requirements, try running the program from the DOS console.
you could try to system("pause") may this can help
#include <stdio.h>
int main(){
printf("Hello World!");
system("pause");
return 0;
}
