i am new to programming and i was doing some of these questions of a book.And got stuck in this question about area of a triangle."Property console is not allowed".Is it due to the math.h?
Because the same code is fully functional on online-gdb.
here is content of lauch.json
{
// Use IntelliSense to learn about possible attributes.

}
]
}
Replace
"console": "externalTerminal"
with
"externalConsole": true
Seems like "console" property is not supported in this version of auto-generated launch.json. However this does the trick to get rid of the warning message for me.
Hmm, now I'm getting "Property externalConsole is not allowed"

I am returning to learning C and was trying to get a basic code to print something to run, and for some reason, after debugging, and writing in the terminal ./{filename}.exe, I get no output at all, and a message in the terminal that says bash: ./test.exe: No such file or directory. attached below is the configuration of the launch.json
"version": "0.2.0",

Thanks in advance!
So i wanted to learn c and got this error after trying to debug it:
Unable to start debugging. Unexpected GDB output from command"-environment-cd path to my c folder". -environment-cd: Usage DIRECTORY

If you want more stuff then ask me.
I'm using visual studio code.
I'm currently using vscode on ubuntu to write and debug a simple c program.
I've updated gdb to the newest version(9.2-0ubuntu1~20.04.1). Whenever I click the debug button a "Permission Denied" error is shown.
Here's a screenshot of the error message
How do I resolve this error so that I can debug my C program with GDB and VSCode? I would appreciate it. The problem has bothered me for days and I can't figure it out myself.
This code snippet below is my launch.json file.
// Use IntelliSense to learn about possible attributes.

}
]
}
When trying to debug in vscode, the vscode generate launch.json config file. When I try to debug, it first tries to compile the source and then debug the exe. I would like to just debug already compiled executable (compiled with gcc -g option).
The json file is:
{
// Use IntelliSense to learn about possible attributes.

"version": "0.2.0",

"type": "cppdbg",

"common.c"

"stopAtEntry": false,

}
],
"preLaunchTask": "C/C++: gcc-10 build active file",
"miDebuggerPath": "/usr/bin/gdb"
}
]
}
Can I make somehow the vsode to not compile but just debug with already compiled source to "program":"${fileDirname}/${fileBasenameNoExtension}", I have compiled to the very same name - no extension in current directory, as the property suggest. So how to make vscode to take this executable as its debug file?
I have found out a few different ways to debug C with the GCC compiler, however I want to have debugging on by default. Is there any way I can do this with a setting in my launch.json in VSCode?

Add these to your CFLAGS: -gdwarf-4 -g3
To do that, run this command:
export CFLAGS="${CFLAGS} -gdwarf-4 -g3"
See this link for more information and this link for running commands in launch.json.
