I have executed the following code in C language:

#include<stdio.h>
#include<conio.h>
#define L 10
void main()
{
	auto money=10;
	switch(money,money*2)
	{
		case L:printf("William\n");
		break;
		case L*2:printf("Super\n");
		break;
		case L*3:printf("hello!\n");
		break;
		default:printf("Wrong answer\n");
		break;
		case L*4:printf("hi!");
		break;
	}
	getch();
}

I thought it wont compile but it is compiling and the output is
Super
Super

can anyone explain me its working??
how can Switch statement take two arguments??

You have separated 2 statements with a comma. The comma is an operator is C and is evaluated from left to right. So you have a comma separated statement as an arguement to the switch statement. This is evaluated as switch is equal to money then immediately switch is equal to 2 times money. Hence switch has a final value of 2 * money. The output then resembles the input and outputs super twice.

Google "comma operator is C"
