Is this a regression compared to 0.29.0?

Can you provide a code sample that fails to format? What is the result of formatting int foo(){return 0;}?

We need more info on your formatting settings. With 0.30.0-insders, a new vcFormat value for C_Cpp.formatting uses a new formatting implementation, which is also used if the C_Cpp.clang_format_style is set to Visual Studio (or if the C_Cpp.clang_format_fallbackStyle is used due to no .clang-format file being found). Is the issue resolved if you change the styles to use Emulated Visual Studio?

after format (the new lines didn't get fixed by the format also)

void display()
{
    int i;
    printf("\n");
    if (front == -1 && rear == -1)printf("\n QUEUE IS EMPTY"); else
    {

	if (front < rear)
	{
	    for (i = front; i <= rear; i++)printf("\t         %d", queue[i]);
	}
	else






	{
	    for (i = front; i < MAX; i++)printf("\t         %d", queue[i]);
	    for (i = 0; i <= rear; i++)printf("\t         %d", queue[i]);
	}
    }
}
int foo() {
    return 0;
}

thank you for the response , I wasn't aware of these settings before .
i was just using the default settings :

 "[c]": {
      "editor.defaultFormatter": "ms-vscode.cpptools"
  },
  "editor.defaultFormatter": "vscode.configuration-editing",`

"[cpp]": {
"editor.defaultFormatter": "ms-vscode.cpptools"
},

now the format is good and back when I added "C_Cpp.clang_format_style": "Emulated Visual Studio"`

void display()
{
	int i;
	printf("\n");
	if (front == -1 && rear == -1)
		printf("\n QUEUE IS EMPTY");
	else
	{
		if (front < rear)
		{
			for (i = front; i <= rear; i++)
				printf("\t         %d", queue[i]);
		}
		else
		{
			for (i = front; i < MAX; i++)
				printf("\t         %d", queue[i]);
			for (i = 0; i <= rear; i++)
				printf("\t         %d", queue[i]);
		}
	}
}
int foo()
{
	return 0;
}

I've filed an issue in regards to the "vcFormat" or "Visual Studio" fallback style at https://developercommunity.visualstudio.com/content/problem/1137727/cc-formatting-doesnt-work-as-expected.html .
